Avoid ban with old save?

Hi, I haven't played in a while and see that there was a ban wave. I used save files and blood point hacks months ago. If I change back to my old save would I still be banned on log in? Would I still be banned for using the old method of blood points etc?

If you just hacked bloodpoints, you don't need to be scared.
I'm hacking bloodpoints everyday since some months and nothing happend.

I got 3 developers in my friendlist, *******, whatsapp, facebook and steam and they checked my savefiles sometimes, because I had some errors and still nothing happend zu me.

Yeah, only BP hack are the safest because logs have no trace after them. However, if for example you have 100h and prestige on all the characters it looks wrong.

But as in every character you add 100+ items (especially purple), it also looks bad.
