He's coming in from three IPs and putting the same bit of spam into a set of articles and their talk pages (and those of anyone who reverts the spam).
He intends to continue however possible:
http://en.wikipedia.org/w/wiki.phtml?title=Talk:White_supremacy&diff=245...
"WE can revert until the cows come home as long as a NPOV is not being maintained regarding this strictly Marxist-PC POV propaganda article."
At what point should an anon user be blocked for spam? Is there a measure of what's spamming on Wikipedia?
(And I am following bcorr's example and trying to keep reverts to no more than three per article.)
