They did not provide a reason. There was no further dialog. I just got a system message telling me I was removed.
I was also silmultaniously shadow banned from Reddit and my posts and comments stopped showing up. I had created a post complaining about being removed as the moderator (the only moderator for over a decade) of a sub that I built from the ground up and donated literally thousands of volunteer hours to over the last 14 years. It had zero upvotes or downvotes or comments and was not visible as an anon user.
In the end, I decided to rip the bandaid off and killed my 16.5 year account. I was one of the early supporters of Reddit (user #7758) and had left Digg for good in May of 2007 after the AAC controversy. They showed their authoritarian side in that moment and I knew Digg had reached their high water mark.
Reddit is at that moment now. They won't be dead tomorrow. They won't be dead next week. However, it will also never be the same, and it's only downhill from here.
Much like Digg. Much like Myspace. I am sure there will be a blurb a few years from now as an addendum in some business journal how Reddit sold to a third party for an undisclosed sum and some Skittles...
The future is the Fediverse and I'm glad I was forced to remove my Reddit crutch and dive in full force.
Edit 1: The messages are starting to come in faster than I can reply. Thanks for all the well wishes!
Edit 2: I'll also add, that I was never going to re-open the sub because I knew Reddit wasn't going to yield. Thus, I was prepared for the outcome. I did hope to string them along for a bit longer and waste resources, but you can't win them all.
