Haha, probably. I'm sorry about that.
The issue I think is mostly due to people thinking they need to crosspost or post the same content in multiple communities like this is Reddit. Since Lemmy is so small, people are likely to see both posts back to back in their feeds, so it's just redundant and spammy. That's mostly why I block accounts that post a lot.
It would be a really nice quality of life feature for Lemmy to add filtering so this kind of thing could be dealt with without blocking.

Because people are sweaty neckbeards who will be pedants at the cost of being tolerable.
Please just use the normal characters for the language you're typing in.
Also, I don't think you need to cross post. Lemmy is small enough that everyone will probably see both posts. I did, at least.
