URL shortening
In April 2009, TinyURL was reported to be blocked in Saudi Arabia. Yahoo! Answers blocks postings that contain TinyURLs, and Wikipedia does not accept links by any URL shortening services in its articles. The Reddit community strongly discourages and in some subreddits, outright bans URL shortening services for link submissions, because they disguise the origin domain name and whether the link has previously been submitted to Reddit, and there are few or no legitimate reasons to use link shorteners for Reddit link submissions.
