Please. Captcha by default. Email domain filters. Auto-block federation from servers that don't respect. By default. Urgent.

Lemmy.world has rules that are up on https://mastodon.world/about - if posts from other instances do not follow these rules the posts will be deleted and if needed the user will be warned/banned. If there is an entire instance that might be a problem, they might ultimately become defederated. Yes this is the last option, but sometimes it's also the only option. Mod and admin tools are quite limited currently and there's just some content we don't want to be linked with.

EH was not defederated because it broke LW rules, it was defeded because it breaks laws. Defeding a porn instance because LW doesn't allow porn won't happen. Defeding a child porn instance will happen for sure.
You shouldn't defed some instance because their rules are different, because all rules are different. That will destroy fediverse before it starts. Everyone who disagrees simply doesn't understand the point of Fediverse.
Did you read that post? I don't think you did because that explains the entire reasoning why it was defederated. Had nothing to do with them breaking the law.
Ok, I guess you're from Belgium. Tell me one thing - is racism legal in Belgium? Because EH is clearly supporting and endorsing racism. That alone makes it illegal. At least here in the UK. There's no need to invent some explanation for this specific case.
So because the rules we put on lemmy.world also match with laws - it's because of the laws we decided to not federate with them? Not because we don't want to deal with that kind of people in general? Because we personally don't like bigots, racists and homophobes? And it wasn't because we didn't want to give them a platform here? Cool, I didn't know.
