So is this strange? Should I have a reaction?

in effect, this seems to me to be "spamming" (in a loose sense of the word) by pm, something that isn't allowed here

i'm sure quite a bit of spamming by pm goes on that no one ever hears about

however, when it is reported, i think the "spammer" should be warned to cease, at the very least - although i believe that many other mods would ban most spam perps, immediately

personally, i think open thread discussion about such an "extra" forum would be fairer to all parties directly concerned, whereas unsolicited pm invitations, etc, should not be agreed as being acceptable - for the reason of not setting a (woolly) precedent, if nothing else
