As far as I can tell, I'm probably not the first person to get hit with a ban for using it - see these threads: 1 2. The only conceivable thing that could've triggered the ban is CleanMem. I've played GTA Online for around 250 hours, and I've never downloaded a mod, never taken any modded money or ammo, never harassed another player, never associated with modders, or done anything else that could get me banned. But a couple hours after that (and after hitting the CleanMem buttons once more), I was booted in the middle of a biker mission and told that I was banned for 30 days and my character would be wiped. It worked perfectly - the memory usage was back down to around 65 to 70% (where it is when GTA Online first launches), and the stuttering was basically gone! I thought I'd found a solution. After about 2 hours the stuttering started, so I alt-tabbed out and clicked the two buttons on CleanMem's interface. Right after downloading and installing CleanMem, I hopped into GTA Online with a friend to do some missions for our biker clubs.

It's a program I've heard of people using for other games with leaks (like Marvel Heroes and Battlefield 4), so I figured it might help here too. I googled 'GTA online memory leak' and found a few threads (like this one) suggesting that CleanMem could fix GTA's memory problems.

I'd dealt with the problem by restarting GTA Online when it started to stutter, but with the loooong loading time every time you restart the game, it obviously wasn't an ideal solution. After 2 or 3 hours, when ~90 to 95% of the physical memory is in use, the game starts hammering my hard drive and causing performance to tank. I've been playing GTA Online for a few months and having a great time, except for one problem - the game slowly eats up all my available memory (8 GB) as it runs. Think twice before using CleanMem or similar memory utilities while playing GTA Online, or you might be banned also. About four hours after I started using it, I got hit with a ban. Tl dr up front: I downloaded a memory cleaning utility (CleanMem) to help with GTA:O's memory leaks on my system.
