People will not get punished for simply having a character that looks similar to someone else
However, the unblock trick counts as harassment and is unacceptable. I know you said you didn't get a chance to get a screenshot of this, but if anyone ever does it to you again really try to get the screenshot
Feel free to pm me about this if you haven't yet contacted a staff member and include any and all screenshots you think are necessary to send in
I'm sorry you had to experience this!
