I fully expect mass posting like that will be the norm on Lemmy, even more than it was on Reddit. Now instead of a handful of subreddits that cover similar context, there are also a handful of communities on here with literally the exact same name. As annoying as it is to see a bunch of duplicate posts in my feed, I can’t say I blame users for doing that when communities are often fragmented here.

This is a phenomenon known as group polarization or attitude polarization. This occurs in person as well. It’s just what happens when people of similar opinions get together --especially groups that don’t know each other very well. There are numerous theories explained in detail on Wikipedia though.

Perhaps it’s more common online since the internet allows people to connect with just about anyone worldwide. People are able to find communities for even the most niche of topics, and online communities have a tendency to become echo chambers.

Well I’m not one to rule anything out…
