I looked up their posts. They likely ran afoul of an anti-spam algorithm. They have an account that was inactive for four years, then it started posting articles only from that blog and almost entirely to /r/technology.

Edit: Their mod team is also relatively small (7 non-bot accounts) relative to the number of users (14 million). For reference, a subreddit I moderate has a quarter million users and 8 mods. That’s 32 times the number of mods on a per user basis. So there is every chance that the modmail message has just not been handled yet.

I really love it when the mods mute you after messaging them about your ban.

I mean, there are a lot of problems with Reddit moderation, but not reading the rules before submitting and getting banned for ignoring them shouldn’t be surprising. It certainly shouldn’t have been a permanent ban and it should have included an explanation as to why they were banned.

Some of the worse moderation on reddit, the admins know this and ignore the problem.
