I exposed this JSON API in the same style as their original API at api.reddiw.com and they banned my account without warning. I explicitly included my reddit username in the user-agent so that they could reach out if they had a problem with it. Nope, straight to banning my decade old account.

The company has turned evil sadly.

Well ya, but they have written posts to mods explaining that their long term goal is to limit scraping.
