I am far from the voice of the WM, but it is my opinion that he would not consider continued posting of the URL of a website which is being debated when the poster has no commercial connection to be spam. I could be wrong, but feel free to ask him.
Personally, I am not very fond of seeing the old "TOS violation" threat thrown out to silence someone with an opposing view. Whether or not that was your intention, it surely could be taken to be that way.
Regarding civility, there is civil, uncivil and thinly disguised civil - all of which I have seen here. Civil or not, this has all the earmarks of one of those neverending debates where perhaps it is past time to agree to disagree instead of continuing to rephrase the same basic information over and over and trying to be the one whose last-word post appears at the end of every thread and individual message discussion.
Since I have no such need to get in the last word and am quite satisfied with what I have posted thus far, I will retire to watch the latest episode of Game of Thrones and the premiere of Falling Skies which I recorded on the DVR.
