Sorry I’m not familiar with Kbin or Mastodon… I just joined lemmy after I saw what happened to /r/piracy (reddit admins forcibly bringing it back online and putting their own mod in charge)
I had a horrible experience with /r/ADHD when trying to communicate with people in the community while I was going through my diagnosis and sought refuge at /r/ADHDmemes instead and there were a lot of people posting there about how terrible /r/ADHD was.
Hopefully I do! It’s a very similar but different experience so far and Reddit has been so ingrained into my memory for years now it’ll be a difficult change.
