I didn't expect a Spammish Inquisition...
Sorry, couldn't resist.
I'd politely PM them (as I would to a regular patron too) about the spam if it is truly disrupting the discussion. I'd also ignore the comment as most people are fond of doing to my nonsensical posts. However, I thought the "spam" was well timed attempts at humour if it is the posts I think you are referring to. There is a point where you can take a joke too far, but often people have different ideas as to where that line is.
