It's annoying AF, much like the habit of people posting comments consisting of "Based" all over the place in recent times. The latter is dying down fortunately, and I hope the R meme meets a quick and painful death very soon.
It's not really a meme. It's from c/196, where the main rule is that you have to post something before you leave, hence why everything is named rule. If you block [email protected] and [email protected] that should deal with almost all of the rule posts.
The block feature is your friend. Use it liberally and don’t feel bad about it.
Seriously, if everyone blocked communities they disagree with or aren’t interested in instead of resorting to the old toxic behaviors that would be a huge improvement.
they are only posting the "rule posts" in 196 communities, mostly centered around lemmy.blahaj.zone, but there's a couple of other splinter subs. If you just avoid 196 you wont see it.
