as you might know, right now there's a known bug of a permanent Nick change possibility.
We're currently investigating in this matter. Since this is a known bug, we appeal to you to not further make use of this known bug. Possible abuse of this bug may lead to a permanent ban.
To be on the safe side, please report a possible Nick-Change done in the very recent past via this bug via PM to me. You will be added to a list which will be spared by a possible future lifetime ban for bug abusing.
Thanks for your understanding.
