reeseroberson (now charity12) is joining communities like woah and posting disgusting videos all over them. Report them as spam, delete the posts and ban him/her as fast as possible. Check their profile to see if one of your communities is on their list and share this alert.
Like RL stress isn't enough... O_o
Edit: Okay, I am currently going through the list of the communities they've joined and try to find the posts they've already made. Then I inform the mods of the communities. If you want to help, do the same. One of them is already down.
