This is probably nothing new, but for me it is: Sponsors spamming their programs using email addresses used to register domains. They are probably only targeting those that own adult domains, but it's still unsolicited.
At least one program I would have likely signed for on my own I now won't touch them thanks to the spam.
Are any other webmasters getting these?
Anyone else have a problem with it or is it just accepted?
I for one, would ask them to stop.
