Yes, i think my longest lasting one actually is like 3 months where i somehow keep winning the appeal. But that's one out of tens of accounts, the standard situation is a ban right away, win/lose the appeal, going for a month before perma ban. Or rarely going on without a hitch for 2 weeks, banned, win/lose appeal, free ride for 1 month. But basically its safe for a month or so after you win an appeal.
This is the appeal for suspicious payment ban im talking about. About the redirect/cloaking ban, usually its easy to win by temporarily deactivating them showing completely safe website and appeal.
