Nulled plugins like RafflePress nulled are pirated copies of premium WordPress plugins that are uploaded unethically to the internet for people to download for free. Moreover, the people that redistribute nulled plugins believe it’s perfectly ok for them to do so. This is because WordPress and any derivative works (like plugins and themes) include a GPL license, so it’s OK to copy and distribute them. That may be true, but it also comes at a cost. As a result of distributing nulled plugins, good WordPress companies like RafflePress lose money, and more importantly, it can compromise the security of websites that use nulled plugins. In the end, nulled themes and plugins are often the reason why websites experience hacking attempts.
