It has great support for blocking yes. In fact, there are curated and/or crowdsourced block lists that one can subscribe to so you don’t have to spend as much time doing it yourself. I am sure there’s one that’s suitable for your needs but I don’t have any to recommend
..you can do that?! I've been dreaming of the ability to block certain words and phrases from Twitter. Blue sky is too chaotic for me… I'm OK sticking with Twitter so long as I can block words and phrases.
or mastodon. or threads. or <anme your platform here>... I hate that the short-text social media world got so fragmented. Twitter was the one place i could go to say hi to my neighbors, complain to a company and get recompense, grow my hobbies with friends, ask almost any restaurant "are you open on $holiday?" and just watch the whole world breathe.
The site has performed more or less the same after the staff cuts as it did before. I say this as somebody who has used it nearly daily for ten-ish years now. Most users I know have the same experience. Maybe you noticed something if you're parked on Twitter for hours at a time, but I try to limit my exposure to people that do that.
I get that Musk is a dipshit and that there are other problems with the site since the change of ownership, but the griping about stability seems to come from people that don't actually use it.
It's becomming slower and slower over time. Feeds often don't load properly. Refresh only works properly manually since the feed often disconnects. Dragscroll (or whoever it is called when you press a button and you can scroll by dragging the mouse up/down) is broken and results in 100% cpu load and a stalled site until you cancel it. But these are just my annoyances, maybe it's just me. I'm switching it out for alternatives as much as possible anyway.
