Just a suggestion to bring up for those affected by the bad purchases who have their games taken away:
A limited time discount on buying the game officially. Where this is by no means the fault of Zenimax (people chose to use shady places at prices too good to be true,) it would be very good PR. It certainly shouldn't be a big discount, but just a little bit will likely get a bunch more people back into the game, rather than deciding it isn't worth it.
I mention this because I participate in discussions elsewhere, and have noted to people that while it is their own fault that they purchased from shady sources... that I would mention this on the forums here. I'd love to turn around, say 'Hey, guess what!' and slap a nice big 'Yep, they discounted it when asked nicely.' in front of those people. Mostly because I know most of them would be happy, but I do admit making the ones who cry foul about everything look a little silly. So I wanted to at least broach the subject!
Thanks for reading my crazy little idea!
