i haven't been using the site much recently. i just logged on for the first time in a few days and i'm seeing so, so many awful posts. this place used to be a really great community, but if it's going to be mingled with shit like this, it's kind of useless. having to constantly educate libs kind of defeats the purpose of hexbear,no?

This script lets you block comments from an instance, although it's a block list not an allow list, so you'll have to grab the list of instances from hexbear.net/instances and add whatever ones you want to block.
