It’s not not hard at all on PieFed: click the username, click More and it says Block that user as the second option down.
Blocking an entire instance takes more clicking, but is also fairly rare so that makes sense. The real trick there is that you need to get to the instance page, and that is easiest by picking a user from it and clicking their instance name - which is in smaller font size, but again this is fairly rare so that makes sense to me. Once you get to e.g. https://piefed.social/instance/lemmy.ml, then you simply click “Block” to never see posts from users on that instance again! The trick of course being that you have to click a user then click an instance to be able to see that button in the first place.
Although that “Block” button was called something different a month ago, when it said “block all users from [instancename]”, and perhaps a few months from now it will again look different? That could legitimately be confusing for people.
On the other hand, Lemmy refuses to provide this functionality at all, no matter how many buttons you click, so having to go through 2 pages (user then instance) is not so difficult compared with the impossibility of doing that on Lemmy!:-P
But what if you don’t imbibe any pumpkin spice - can Autumn still be said to have truly started in that case?
