Defederation with Instances that Allow Loli and Shota

I won't pretend I'm knowledable enough to debate the pros and cons of defederating in the fediverse. I've just been blocking communities centered on topics that I don't want to see, including the ones you're talking about. I've been on the internet since the early days though, so a drawing before I can block the communities in question isn't going to scar me.
