Along with more general videos about FIFA, the YouTubers posted about making bets using FIFA coins, ignoring concerns that they could be breaking the law. According to the BBC, the U.K.'s Gambling commission is concerned that children may be drawn into illegal gambling after watching this kind of content.
The relevant videos have been blocked to U.K. viewers, with videos like "FUTGALAXY - FIFA BETS, FIFA PACKS & FIFA 16 COINS!" being replaced with a message saying, "This content is not available on this country domain due to a legal complaint from the government."
