I've owned this account for 4 years and Derpuh_xD is just way too silly: I was gonna make a new account with a far better name but I just wanted to know if alting is illegal. I guess bypassing a ban would be one problem but they could just IP ban or I could announce my alternate and they could ban both. . . Anyway, I don't hack so I have no worries.
As long as you aren't using it to bypass a ban or anything, it's allowed. Heck, I even have an alt. I'm going to rename it NotMap_Turtle after the update. Just let everyone know and not use Derpuh_xD anymore
