What type of botting do you normally do on this account? Gather, level, lazyraider, pvp? I say just let the suspension run out, wait a few days before doing anymore botting and then start up again and just don’t go overboard for the first week or so. This is just precautionary. Many would say just go back to botting whenever you like.
What was the suspension for? Abuse of the economy? If so, that is their catch all for believing you to be botting but not being able to detect the software. Run a dungeon or two, chat a bit in trade, be the normal guy for a few hours and then back to business as usual. In the end you paid for the account. No reason to let it go inactive or sell it over one little suspension.
