The Black Mafia, also known as the Muslim Mafia, Muslim Mob, Philadelphia Black Mafia, or PBM is a Philadelphia-based African-American organized crime syndicate.
 The organization began as a small criminal collective, known for holding up neighborhood craps games and dealing in the illegal drug business, but at its height of operation until about 1975, it managed to consolidate power and control a large portion of criminal activity in various African-American neighborhoods throughout Philadelphia, the Delaware Valley, and South Jersey, including Atlantic City.
 In addition to drug trafficking, burglary, and armed robbery, the Black Mafia was also engaged in traditional organized crime activities such as extortion, racketeering, prostitution, loansharking, number running and other illegal gambling rackets.
Around the world are countless groupings of individuals who deal exclusively or through a mix of legitimate and illegal activities.
 These Organized crime groups or criminal organizations are a transnational grouping of highly centralized enterprises run by criminals for the purpose of engaging in illegal activity, most commonly for the purpose of generating a monetary profit.
 The Omnibus Crime Control and Safe Streets Act of 1968 (federal statute - Public Law 09-351) states, "Organized crime means the unlawful activities of members of a highly organized, disciplined association..." They are called a number of different names including: the Mafia (US, Italy), Yakuza (Japan), Chinese Triads, the Irish Mob, the Neapolitan Camorra, the Calabrian 'Ndrangheta, the Indian Mafia, the Unione Corse, Serbian Mafia, and the Bulgarian mafia.
Prostitution in Hong Kong is itself legal, but organised prostitution is illegal, as there are laws against keeping a vice establishment, causing or procuring another to be a prostitute, living on the prostitution of others, or public solicitation.
Franeleros are people who have as main activity guarding or keeping an eye on cars parked in several streets in certain places in large Mexican cities, getting a tip as a reward, which sometimes is established by them.
 The term comes from the Spanish word "franela", meaning flannel, which is a small piece of soft light fabric (normally washed out red or gray) which they use to wash the cars if they are asked to, or to simply wave it around to give parking indications.
 "Franeleros" are sometimes also known as "cuida-coches" (car keepers) or ""viene vienes"" (literally "come come"), which is the phrase they commonly say while giving the parking indications.
 In 2007, due to the criticisms around this controversial "occupation" (mainly extortion, grand theft auto, relation with organized crime and illegal use of public space) this guarding activity became illegal in Mexico City, but it is still widely practiced.
 In areas where parking meters have been installed, franeleros no longer operate.
Indoor cycling, as an organized activity, is a form of exercise with classes focusing on endurance, strength, intervals, high intensity (race days) and recovery, and involves using a special stationary exercise bicycle with a weighted flywheel in a classroom setting.
 It is commonly called spinning.
Prostitution in Pakistan is a taboo culture of sex-trade that exists as an open secret but illegal.
 Prostitution is largely based in organisational setups like brothels or furthered by individual call girls in the Punjab province of Pakistan.
 The sex trade is deemed illegal in the country due to the declaration of extramarital sex as an immoral activity.
 Pakistani prostitutes, thus, operate underground and in spite of the legal difficulties, prostitution in Pakistan is prevalent.
 In some areas of the country prostitution is strictly illegal and traditionally punishable by death, especially in the Federally Administered Tribal Areas (FATA), Khyber-Pakhtunkhwa and Balochistan regions.
Youth service refers to non-military, intensive engagement of young people in organized activity that contributes to the local, national, or world community.
 Youth service is widely recognized and valued by society, with minimal or no compensation to the server.
 Youth service also provides opportunities for youth development, youth voice and reflection.
 This may take the form of a youth program where young people are recruited, offered leadership opportunities, participate in activities that improve the community, and are trained and mentored.
Whispers and Moans () is a 2007 Hong Kong film directed by Herman Yau.
 It is based on the 2006 book "Whispers and Moans" by Yeeshan Yang, investigating the Hong Kong sex trade.
 It has a Category III rating in Hong Kong.
Organized crime is a category of transnational, national, or local groupings of highly centralized enterprises run by criminals who intend to engage in illegal activity, most commonly for money and profit.
 Some criminal organizations, such as terrorist groups, are politically motivated.
 Sometimes criminal organizations force people to do business with them, such as when a gang extorts money from shopkeepers for so-called "protection".
 Gangs may become disciplined enough to be considered "organized".
 A criminal organization or gang can also be referred to as a mafia, mob, or crime syndicate; the network, subculture and community of criminals may be referred to as the underworld.
 European sociologists (e.g. Diego Gambetta) define the mafia as a type of organized crime group that specializes in the supply of extra-legal protection and quasi law enforcement.
 Gambetta's classic work on "the Sicilian Mafia" generates an economic study of the mafia, which exerts great influence on studies of "the Russian Mafia", "the Chinese Mafia", "Hong Kong Triads" and "the Japanese Yakuza".
Spoofing is a disruptive algorithmic trading entity employed by traders to outpace other market participants and to manipulate commodity markets.
 Spoofers feign interest in trading futures, stocks and other products in financial markets creating an illusion of exchange pessimism in the futures market when many offers are being cancelled or withdrawn, or false optimism or demand when many offers are being placed in bad faith.
 Spoofers bid or offer with intent to cancel before the orders are filled.
 The flurry of activity around the buy or sell orders is intended to attract other high-frequency traders (HFT) to induce a particular market reaction such as manipulating the market price of a security.
 Spoofing can be a factor in the rise and fall of the price of shares and can be very profitable to the spoofer who can time buying and selling based on this manipulation.
 Under the 2010 Dodd-Frank Act spoofing is defined as "the illegal practice of bidding or offering with intent to cancel before execution."
 Spoofing can be used with layering algorithms and front-running, activities which are also illegal.
 High-frequency trading, the primary form of algorithmic trading used in financial markets is very profitable as it deals in high volumes of transactions.
 The five-year delay in arresting the lone spoofer, Navinder Singh Sarao, accused of exacerbating the 2010 Flash Crash—one of the most turbulent periods in the history of financial markets— has placed the self-regulatory bodies such as the Commodity Futures Trading Commission (CFTC) and Chicago Mercantile Exchange & Chicago Board of Trade under scrutiny.
 The CME was described as being in a "massively conflicted" position as they make huge profits from the HFT and algorithmic trading.
