They’ll get banned eventually for upvoting something on a gaming sub that mentions Luigi’s mansion. Then they’ll be confused for a while and move to the next app

Perhaps. I found those types of things the easiest to replace. Plenty of people on Lemmy talking about news / politics. You guys don't have enough niche hobbies though. I do often miss my underwater basket weaving sub and having a reliable stream of cake fart porn.

I got banned yesterday and did not know what Lemmy was until I did a search for Reddit alternatives.

This is true. I do a bit of shepherding myself, and many have never heard of Lemmy. Don't give up on them!
