Just ran into something weird for the first time. After spam cleaning a thread and having it moved to a hidden section, the page kept freezing, RAM for that specific page went up over 1GB and at the end it gave the "Shockwave Flash has Crashed" error in chrome. Before Shockwave would crash, I was able to scroll way past the footer of the page and during the entire time the bottom of the page would say "Waiting for static.ak.facebook.com". I though it may have been some issue with Facebook but it was only happening on that one specific page. After about 5 times I am not able to reproduce this anymore but I am curies if anyone has an idea of what it could have been. My wild guess was that Facebook did not like the content in that spam message but I doubt that is connected..
