I'm happy to help out a bit, it could even be a central thread instead of many loose threads.
Of course, this will only work for people who have a publicly staked address and can still sign from it, as they're easily checked. Anybody wou can't sign from a staked address will just be on his own (like now).
Exactly what i would say.
I don't know if theymos or Cyrus are taking a look on ips, pms and crypto addresses in order to get more information about the case, but for the majority it is is quite easy to verify that the hacked account is linked to the one that could verify an old staked address, this member can take back his account in few days and if it requires digging it could be done later imo. For the one that he doesn't staked any address and have another method, he needs to wait longer to be verified by admins.
No need for another admin and btw any information about badbear (previous admin) i didn't find a topic talking about him, he couldn't just look for this issue in case he doesn't have too much time to do admin regular activities?
