If you've admitted you're suing alt accounts to join in the same campaign, then you need to accept the punishment for getting red tag, anyway you can still access this forum, posting and join a campaign which accept red tagged user too, your journey doesn't end.
because it is clear from the account you can see what his goals are in the forum. and when negative tags will limit it from participating in bounty campaigns. then I'm sure he will discard this account and be active with his other accounts.
and when he does then in the future he will be caught again because he will not learn from his present mistakes.
