Anybody who has played the PC version of GTA Online knows how problematic cheaters are.
It's especially brutal for any big-name players with an online presence, as their fame inevitably attracts modders to mess with them. Sadly, GTA Online doesn't deal with cheaters as well as its fans would like.
Most big-name online games have a problem with cheaters. It's not exclusive to GTA Online, but it's arguably worse for this game than other titles. Popular GTA YouTuber TGG recently released a video talking about this problem.
