For myself, I used the tools available and blocked the entire threads.net domain. It's nothing personal against anyone other than Mark Zuckerberg. I just think that there are too many avenues for bad faith fuckery coming from that domain, and I want no part of it.
@Joe_Hill) Do a search for users with @threads.net; 2) when you find one, click on their profile; 3) in the profile, pull down the three dots menu on the right; 4) select Block Domain.
