Piracy and Star Trek communities had a lot more success migrating their communities over to lemmy compared to other communities. Not 100% success as many opposed to the migration (I remember seeing big drama on r/piracy back then, and lesser drama on r/startrek), but a good chuck of them was successfully migrating to lemmy.
Edit: wait, I didn't realized it's @db0 himself that made this post. Man, I don't know how you're able keep going with encouraging redditors to migrate to lemmy with how redditors that stay on r/piracy was treating you. I say good riddance! Your hard work paid off!
