It appears I have been banned from Reddit for good. Their automated mod tools have improved to the point where I can't have an account for more than a few hours before it's permabanned. I don't even need to post anything. Whatever script they run must know based on either your IP, your phone number, or accounts associated through gmail.
It all started a few years ago when someone posted a really good looking plate of cinnamon rolls on r/foods. I made made some stupid comment about them looking so good, I wanted to get them pregnant. Anyway, I was banned from that sub for saying what I did. I was later banned from r/askreddit for a comment that I didn't think was controversial, but was flagged as hate speech. I really liked participating in both of those subs, so I created an new/alternate account so I could continue to participate.
As soon as I posted in r/askreddit again, their automod tools flagged me, and I was banned immediately from the sub. About an hour later, I was banned from the site as a whole (first time) for circumventing a previous ban. So I created a third alternate account and decided to just not post in either of those subs. That worked for about four years until I slipped up and accidentally replied to a comment in one of them, resulting in another permaban from the site. I made a new account, and that one lasted about six months before I slipped up again. I guess for a long time, it was mostly just the subreddits that used those kind of detection tools, but it looks like Reddit as a whole has begun to utilize them. Any alternate I create gets the hammer within 24 hours regardless of my activity.
I've moved onto this new site called Lemmy. It's the closest alternate I've found so far. It's only got 50K users at this point. I'm hoping it sticks around.
