Roar!
We made the mistake of signing onto a recall our state governor petition not realizing that becomes a public information data string.
Fortunately I used a total junk email address, (which btw was maintained as a free service from our ISP), point is because those lists go public I've been receiving various political spam pitches for years in that email inbox. Once every month or two I go in there and dump several page loads of ad spam crap into the trash, it's that pervasive.
Yep there is no shame for online ad spammers, and pro tip: the real meaning of 'Free' on the internet is more like, 'Free for All' spam adds now coming your way. :-)
