Looks like my account got unbanned at some point between February and now.
I see there are a couple other topics with this issue, but I felt like I should make my own. I bought AC this morning for the affixing scratch, and didn't think anything of it until I tried to switch characters and the game said my account had an issue. When I closed the game, Steam said it detected some suspicious activity and restricted my account. When I wrote a ticket to Steam, they got back to me within an hour, with a reply that was basically, "Woops, my bad lol. We fixed it."
Now, my Steam account is fine, but I'm getting a Suspension 816 message when trying to log into PSO2. I wrote a ticket in the (I think) correct place on this site after some navigation, but have heard nothing yet. I'm not expecting to hear back today since it's a holiday, but that means it's going to be at least one whole day my premium goes to waste for some issue I had no control of.
After a week of no response, I'm pretty much giving up hope on this. I don't want to spam this forum, so I won't be posting about my suspension anymore, unless someone wants to have a conversation about it. But I wanted to post what I feel is relevant "evidence". Not because I think it'll help my case, but because I'm hoping it'll help someone else who is in a similar situation understand why it's happening to them, since it’s pretty obvious that no concrete information will ever be given out about this kind of issue.
Thursday morning, I bought $50 worth of AC for the affixing scratch. After purchasing and doing a couple pulls on the scratch, I switched characters and got this error:
When I closed the game, I had a pop-up message from Steam saying that my account had an issue, and that a restriction had been placed on my account, stopping me from making any purchases. I contacted Steam, and they got back to me in about an hour (on Thanksgiving) and lifted the restriction:
They didn't specify, but I'm assuming the restriction happened because, when I first went to purchase the AC, I accidentally added it to my cart twice, and cancelled it before adding the money to my Steam Wallet. The cancelled transaction showed up as a failed transaction in my history:
After that was resolved with Steam, I immediately received an 816 when trying to log into PSO2.
