I rarely, if ever, use PayPal.

The other time I used it to buy a copy of Demigod (by Gas Powered Games), a fairly simple-minded but graphically rich third-person combat game.

Within days of placing that order, I started to get spam to my PayPal address, where I never received spam before.

I only used the PayPal address in the order and license process, and never used it for anything else with them.

That's a filthy, filthy, filthy business practice. Either someone at Stardock who has access to order emails is covertly selling them, or Stardock themselves are doing so.

It is illegal, too.
