I have several list-building oriented sites in small very targeted niches where i am getting hammered by email opt-in spam - i'm seeing literally dozens of sign-ups every day on multiple lists where someone is adding a keyword as their name (currently its Denistas Barcelona, and before that it was Samsung HDTV 1080).
Of the several hundred of these i checked, each one has a unique gmail account.
About half of the sign-ups get confirmed, the other half never do.
I'm guessing this might be blog commenting spam gone wrong, but that's really just a guess.
I talked to Aweber support and they told me there was absolutely nothing i could do about it other than manually go in and remove the confirmed subscribers. i can't do anything about those that never confirm (expect make the lists single opt-in and delete them all everyday).
My questions are:
1. Any idea what software is doing this?
2. Is there a way to prevent it?
3. Anyone else dealing with this?
