I usually browse Lemmy hot and just block any communities I don't find interesting. As I understand it, the blocking seems to be done by your instance. So is there a maximum number of communities a user can block on the instance side? And what is it?

I'm asking because I used to run into the maximum number of blocks on my Reddit client and it was pretty annoying when my oldest blocked subs would reappear again.

I think they used the multi-reddit list as the back-end for subreddit block list. I too ran into the limits.

I don't think Lemmy has any limit, but performance will likely degrade and it is entirely possible that your personal block list causes overload of servers with lots of data in them.

I imagine they must have some limit, otherwise that would be an easy exploit, just creating a practically infinitely long block list to crash the instance. I would get it if clients have an unlimites blocklist, but not instances.

Perhaps you are unaware of just how unstable Lemmy has been since late May.

Fair enough.

If that's the case, wouldn't it make sense to put a genre/label onto sublemmys? Because e.g. I block all "bread for the people" subs (i.e. sports). And being able to block "sports" would be much easier.
