Noone gets tagged for having an alt account. Tags come into play when users enroll their alt accounts in the same campaign. Essentially cheating a signature campaign and sometimes bounty campaigns.
It's totally legal to have alt accounts, even some staff have alt accounts. Just don't abuse the system with them. Don't start conversations back and forth in a thread between your accounts. Don't merit your accounts.
Good to clear that up, thanks. So alt accounts can be used to organize information for more than one blockchain project and some other legit purposes.
