1. Followed the instructions to redeem the code.
2. Automaticall asks me for a subscription payment. No.
3. Account sits in limbo saying it needs to be activated, clicking that asks for a subscription payment.
4. Discord support said to click a button to "delete the forward" which removed the appsumo code from my account.
5. Appsumo code now says invalid/redeemed, so I can't follow Discord support.

This looks like it's pretty much just a big fat scam and I'll definitely dispute the charge in a few days if this isn't resolved.
