There have been many problems with alts in the past. We've had fights break out over them, bans handed out, and many (including myself) get paranoid about a user being an alt and whether or not they have a malicious intent.
Therefore, enough members of the Wiki staff including Zener herself have voted to add the following rule directed toward alts:
If you join as an alt and fail to tell the entire chat you are an alt, being caught will land a ban on your alt and your main account for a week. After that, a month; yadda-yadda, so on, so forth.
We need to keep this Wiki's logs clean to make sure the Wiki is safe and alts take up that log. If we don't know an account that appears, chances are, we will be suspicious of that account for awhile. That's why you must tell us your alts. It's for your safety and for the staff's peace of mind.
Thank you and continue to enjoy your time here on Zener's Wolf Pack.
