Frequently asked questions
How does AltShield find alt accounts?
It compares various network and device signals, and the accounts members connect, with earlier verifications, also across servers.
Will my staff see who the other account is?
Staff see that an identity matched. If the other account is on your own server they can see which one; matches from other servers never reveal the account or the server.
What happens when an alt is found?
You choose: flag it in the log, hold the member for manual review, kick or ban.
