“...Does GAB filter out moonbats?...”
What I’ve seen so far is that they’re just totally ignored....totally.
It’s like a screaming imbecile in a padded room....no one pays them any attention.
They don’t filter... at all. If you find a moonbat or Nazi, you can mute that person. If enough people mute some of the users, nobody can hear them scream.
Once I muted about 15 people from the general Gab feed, the quality of the postings improved a lot.
I’d bet the iOS progressive web app has increased the postings on gab.
