since when its not allowed to have alts?
It's perfectly allowed for untrustworthy users to have alts; that's why I only gave them negative trust instead of reporting the tell-tale PMs and getting them both banned.

Having multiple accounts and account sales are allowed, but account sales are discouraged.
So why did he get tagged ?
If you tagg him you should also tagg the accounts of suchmoon such as glem or tagg any other known alt.
Also who are you to decide if somebody is untrustworthy or not ?Based on what evidence are you making these taggs ?
Cause currently i can only see that you are abusing the trust system which has been confirmed by theymos.
