About 4:10pm EST, someone was using server messages (the kind that black out the entire screen and have the words right in the middle) to write random things, like Backstreet Boys lyrics and random quotes. Game was still going on while this was happening so people were being attacked by zombies while they couldn't see. I took a screenshot then got off ASAP so I could report. http://cloud-2.steampowered.com/ugc/542929606120181138/C3CCB7000BC75B5A1E935756AF48ED5B81BBF361/ Thought it was admin abuse at first but people claimed otherwise, I hope they're correct.
