I had 3 accounts that were working well, but I had abandoned them for various reasons. Then, when I created the 4th one, I noticed something strange. Nobody was interacting with my posts or comments at all. No upvotes, no downvotes, no replies. I couldn't use the chat function at all, and regular DMs seemed to also get no reaction. When I used my other account to see comments or DMs of this one, I couldn't. They just didn't exist. When I tried to open this new account's profile page, it just told me the profile didn't exist. I tried creating 2 more accounts, and it was the same story. Finally I posted in r/help (iirc), and instead of getting a reply, I was told that this question had been answered before and my post was removed. The thing is, I had searched for an answer, I couldn't find anybody describe a problem like this.
Eventually, I tried making a new email on Proton Mail, and register a new account using a VPN. That did the trick. But this experience left such a bad taste in my mouth. I cannot use any platform that treats me like shit. I dunno what was the issue there, but Reddit could've told me. Instead they decided to play this weird game with me. This is the first time I've ever seen a website do something like this. So I just got pissed off and left.
