Everything remains intact, in case by chance you happen to get the account unsuspended. But during the suspension period, no one can see any tweets or replies made from that account.
Almost no one get their account back once they get suspended. I've tried numerous times to explain and stuff like that, after a lot of e-mails they finally responded tell me my account will remain suspended.
The whole idea with automating your tweets with TA is to make it look as HUMAN as possible. An unverified account that puts out 500 tweets with links a day looks shady and sends up red flags everywhere! Throw some tweets in the mix that don't have links. Look for quotes/questions/etc. Engage with people every now and then.
