Before the subreddit got banned, I and other r/ConsumeProduct mods compiled lists of active users who commented or posted. I'm using a bot account to send out PMs to all of them, starting with the most active ones. Many of our top users though are now unfortunately already suspended, shadowbanned or deleted.
It'll probably get banned for spam, but I don't really care anymore because Reddit banned all of my accounts just for moderating the sub. They even changed the passwords of my and most other mods' accounts so you can't even log in to them anymore (it now just says "Wrong password").
If any of you still have a working Reddit account, I also suggest that you let people know this website exists, especially in threads about the ban wave on subreddits such as r/WatchRedditDie, r/DeclineIntoCensorship, etc. That's how we would hopefully be able to regain at least a part of our userbase.
