I disagree wholeheartedly. I feel that by his mere presence here, he is harming the members.
Imagine if any of us were (god forbid) taken to court. There we are showing our warning pages, our links to the IRCA, etc in order to prove that we have no wish to be associated with children in any way.
And then the District Attorney asks something like whether or not we frequently visited a message board that was also frequented by a person who admitted to putting pictures of underage children engaged in sexual acts on his website. No matter what you say, they have printouts or screencaps of you posting in a thread where SexEd posted.
There goes your character, at least, if not your defense. Conversing with an admitted pedophile. Even if you don't speak to him (which we all have), his mere posting in a thread that you've posted in constitutes being involved in a "conversation" with him. Guilt by association.
