No not yet but I think there's plans to make it possible.
I mean our goal is to not have to do this, but its up the individual instances to protect their own reputations and neither of the ones we blocked have done that so far. If they clean things up and the communities overall opinion of them changes then we can consider federating with them again but as of now they have too many people against them.
Yeah good point, I just added that it goes both ways. As far as blocking single communities go I don't have all the details but I've been told we've done it for one so far.
Yeah we've discussed it more and we decided we're defeding exploding. As far as why we're defeded from lemmygrad, they're just known for causing problems similar to exploding heads and we just want to keep things drama free.
Yeah they haven't become a huge issue for us yet, but they have for other instances, and most of our reports of "racism" have come from things posted to exploding. Deferedating isn't to send any sort of message, its just to prevent having issues with them in the future.
