The lemmy.cafe instance is defederated from lemmy.ml and hexbear. If you use a lemmy.cafe account, you won't see any post/comment/communities from users of those instances.
For me, this works better than having to block users one by one. Lemmy is only tolerable to me because of this option.
The best way is to make an account on a server that doesn't federate with them. Sh.itjust.works, lemmy.world, and most other large servers are defederated from hexbear and lemmygrad.ml.
Apparently lemmy.cafe is defederated from those as well as lemmy.ml. Be aware that a good chunk of major communities are hosted in lemmy.ml, so you won't be able to access those if you're defederated.
Unfortunately even if you block them, you will still see posts and comments that users from that server make on external communities. It's only by being fully defederated that you won't be able to see any of their content at all.
Sh.itjust.works is not defederated from hexbear lol. I can speak from experience that they still show up everywhere.
Yeah I guess that's true, they are defederated from us but technically we aren't defederated from them. But they still can't see anything that SJW users post or participate in our communities. And same for lemmy.world, etc.
So you only really see them when they comment on lemmy.ml communities for the most part. There are a lot of lemmy.ml sublemmies to be fair.
Thank you. I'm currently on lemme and it's a good instance. I guess I should hop over to lemmy.world if they already defederated them.
Lemm.ee is a really good server but if hexbear and lemmygrad annoy you, then it's not the right fit for you.
Ya, it's sad but true
You can block full instances via a PC. I generally surf lemmy using Boost and I wasn't able to do on my phone.
But go to your settings>blocked>instances and type in the instances you want to block.
Also fair warning, you're most likely about to get brigaded by both instances
Mobile Web too.
What's important to note is it blocks all the subs from that instinance, but not posts those users make to other instances.
And you'll still see all their comments, but you won't get notified if someone from those instances reply to you. You can still see them and reply back, but you won't be notified
It's better off blocking users one by one because of all the people with alts. Cut their head off and two more grow in it's place
Nah, I blocked .ml, hilariouschaos, and a couple other troll instances.
Worked out great so far, I've even thought of blocking some of the "dead" instances because that's where troll accounts usually come from.
The main issue is accidentally stumbling into a sub on their instance, anywhere else and mods/admins can step in.
But there is zero reason to ever comment or even see a post made on those instances, because the worst users on them are the mods/admins.
So you just stop going to their house where they make the rules.
Boost has that option under settings>filters & blocks>muted instances. You have to type in the instance address but it worked for me at least.
Weird. I couldn't do it, but it's all good. I can remove blocked instances but not add them on boost. Might be a bug I should let the devs know about
Settings shortcut: Filters > Instance filters
Is this the one?
You can also block the instance at the account settings level (Blocks tab). That way you will not see posts from these instances on both the webUI and mobile apps.
Sadly it doesn't have a toggle to block comments and post from users of these instances made on communities outside of these blocked instances
Thank you. I think I might have inputted the instances in wrong. 
Mine doesn't have @ signs. This might be easier to do in the lemmy web UI than within Sync. When you start typing an instance name, it will pop up a list of matches that you can click, so you don't have to worry about typos or syntax.
Thanks I'll try that.
Feel ya, every now and then I do find an interesting conversation on both, but most of the time its just annoying spam at best.
I saw an article about how shit the American economy is and how amazing of a job Xi bear is doing in China and I'm like, no.... No I'm done.
Can't wait for mbin to have the same feature. Those two instances might as well be official Russian servers.
It already does, and was in kbin day one (of reddit Exodus). Look in your settings for the block domains area. Unfortunately the feature to add a domain block only worked on desktop for me.
I tried that feature. It only blocks links / posts with those servers - as in, if somebody makes a post and puts a link to that server as the topic, then that post won't show up. Unless a new feature was introduced, I'm afraid that's it.
Three dots on a post > filter > filter instance
Doesn't seem to work.
Which part isn't working?
I think I figured it out. I removed the @ and I think it worked.
Oo good to know, thanks for letting us know
Thank everyone on this forum for being so helpful.
You can block instances in Voyager. I don't know if it blocks everything though, like comments from a blocked instance account etc.
