I'm not sure if I got spam today also. I had a new PM with a referral link. I simply deleted it because I thought it was just a reply to my downline thread (I only accept downline messages in the actual forum). However, it didn't say anything about exchanging links or my thread. If I would have thought more of it, I would have reported it, sorry.
I don't think most people realise that spam is an international offence and that you can be prosecuted in the recipients country as well as the originator's country...
