1. having multiple accounts is allowed, selling your account is allowed but frowned upon, and using alt accounts to cheat bounty is not a bannable offense (unless your previous account has been banned for whatever reason) but you'll get red trust from members who think you deserve it.

2. would you mind elaborating on what "cheating with altcoin" means?

3. what do you mean when you say "concentrated account"?

4. I sure hope so, recycling your bounty reports to deceive your bounty manager deserves a red trust.
