for the most part, if you're only using the PS3 CFW to play games, you should be safe. As long as you don't alter the EBOOT file with a hacked version. I used a PS3 with CFW from the time CFWs were available until about 2016 before getting banned. The ONLY reason I got banned is because I was playing Destiny (which requires you to sign into PSN) and then I switched over to Call of Duty with a modified EBOOT file and forgot to sign out of PSN after playing Destiny. I wasn't even playing multiplayer on CoD, I was just playing around with a modified EBOOT. First time I had messed around with one. It is best to use a separate account on a PS3 with CFW as well. If your account gets banned, you can't use it for anything involving PSN...so it would be banned on Vita, PS4 and the upcoming PS5. If it's a console ban, then you CAN purchase a ConsoleID and get back online but there is no guarantee that it will last. I've been fortunate enough to purchase a ConsoleID ONCE and it's lasted for about 3 years so far. However, i'm not using modified EBOOT files anymore.
