Nah, just make it a week or less at that point. I'd be pretty pissed if I dedicated 3m of my life to a game and had all that wiped just because other people decided to be petty, especially considering how slow Square support is. Bots will just be continuously making new accounts anyway so no real reason to target people with months under their belt.
I can assure you, as I experienced when my ex got hit with an RMT based suspension, they'll go after your account even if the encounter happened months prior if there's evidence of it happening (odds are the person he bought from got caught and they went after their previous trades or he tripped a sensor with the trade itself and the backlog finally got caught up to him).
