The specific spam (which has couple of versions) is posted on many chans (maybe on everywhere but not on 4chan because they block everything), and several boards on Endchan (not sure about other places, I guess the same situation).
It is done on couple of days a week. Sometimes there are longer gaps. A day they do it 1-4 times.
It's far from sure that there is any cp on the sites they link. I hope noone is stupid enough to open it.
