Tonight while making the interest check thread of a roleplay, an In Character thread of a different roleplay that I'm also the GM of was more-or-less "invaded" by a user who does not belong. This user goes by the name "soha" and their post can be found as post #5 on this thread:
They are not one of the players accepted during the application period, and their post doesn't even appear coherent. In fact, the post they made on my thread was the first post that account has ever made, and the sign up date of the account as seen on their profile is September 21, 2013.
I did report the post earlier tonight, but I wanted to make this thread to reinforce the presence of the situation, and perhaps shed light on what can be done to prevent it from happening again. I come here to ask if there is some way I can make it so that only users I select can post on a thread I've made, or if there is any other way to erase and/or prevent posts like soha's? Any help at all would be appreciated!
