Currently, there is no account verification for users. This means I can create an account under any [User]name and pretend to be them.
If you made it so people over the rank of TL2 had to verify their accounts, the impersonation risks would go down slightly.
How it would work
User A is trust level 2 and must verify their account. They can DM a mod, and they will give them a code to set their desc to. When their desc is set to the code they get a verification badge and get let into the verified group.
The user goes to a verification game, is given code(a discord webhook saves the code to a channel) and when the user sets their luahub desc to their code a mod would enter them in the correct groups and would be given the right badge.
