Here's how this works:
- Email that I receive can only possibly come from the sites each address was used on
- The address is only use on one site
- The address doesn't exist outside of that site's database
- Any mail going to that address is spam (unless it originates from the site where it was used, of course)
-- The only way the address can be receiving spam is if the site is selling user data
-- or more likely, got hacked / is leaking data (data stored in an open directory)
This is an ongoing list of scams. Anyone spamming these addresses has collected them from dumped databases. Anyone using stolen information to spam a service / product isn't going to be legitimate in any way.
I also suggest reporting these scams to their "affiliates", aka sites like CoinPayments, to make it more difficult for them to scam people.
I've finally been annoyed enough by these scams that I am making this thread, therefore I only have today's first spam. I'll update regularly.
