Trust me, I've played GTA Online since the day it launched (or the week afterwards rather since the servers were really shit at launch), they only ever did anything about cheaters if they cheated money.
I remember all the early money exploits and car duplication glitches, those were usually hotfixed in a day while other (game-breaking) bugs existed for years...
I'm hoping they do something actually effective against the cheaters, so far the only thing they havd accomplished is screwing over their Linux users. I went to pick the game up again the other day and found it no longer functions for multiplayer under proton because they are too scared it'll be used for hacking. Meanwhile everyone and their mother is bitching that thd cheating still exists so obviously Linux wasn't the issue.
Woops, Mutahar accidentally indirectly killed it by giving it coverage.
He covered it about two weeks ago trepedatiously, thinking the project was awesome, but stating that Rockstar could kill the whole thing if they became aware of it...
"Due to the unexpected attention that our project received and after speaking with Rockstar Games, we have decided to take down the Liberty City Preservation Project."
The above linked almost half million view video is almost certainly the 'unexpected attention our project recieved', not the inline linked tweet IGN provided with less than 300 retweets.
