Where exactly were the attacks on posters in any of the deleted comments? Care to expand on just what those "legal reasons" are WP? Did someone threaten you and/or the site? 
I think you know the comments made towards another poster before the post was edited. Wonder why it got edited?
As for legal side of things, no the site did not receive a threat as you put it BUT there were statements made that were made without foundation and fell into the grey area. And under the legal advice we have received many times anything grey gets removed. Has done since the site started and that won't be changing
