Actually, me too.
If there's any technical assistance I'd like to see implemented, is a tool that could warn the responsible clan that something suspicious is going on. An extra pair of eyes, so to speak, be it of a technical nature. Perhaps, the approval of the wanted username could be put on hold, until it got approved by the clan. Maybe it could be approved temporarily, and be renamed in case of objections.
It's not just (possibly vicious) willful impersonation, as was the case of Wassercrat (vs. Wassercrats), but also people that request several similar names, in order to correct a typo. Just check out the list for that new fairly new user: Iam2told4this, Iam2old4this, and 2old4this.
And then there's numerous examples of people who have a name very much like the real Anonymous Monk: Anonvmous Monk, Anomynous Monk, Anonyrnous Monk, Anonamous Monk, Anønymous Monk, An Anonymous Monk, to take just the most striking ones.
Now the latter can be seen as a joke, and doesn't actually hurt anyone. The case for Wassercrat and possibly im2. and bart., is different, IMO.
