Please. Captcha by default. Email domain filters. Auto-block federation from servers that don't respect. By default. Urgent.
And yes, to refute some comments, this publication is being upvoted by bots. A single computer was needed, not "thousands of dollars" spent.
The admin https://lemmy.dbzer0.com/u/db0 from the lemmy.dbzer0.com instance possibly made a solution that uses a chain of trust system between instances to whitelist each other and build larger whitelists to contain the spam/bot problem. Instead of constantly blacklisting. For admins and mods maybe take a look at their blog post explaining it in more detail. https://dbzer0.com/blog/overseer-a-fediverse-chain-of-trust/
db0 probably knows what they're talking about, but the idea that there would be an "Overseer Control Plane" managed by one single person sounds like a recipe for disaster
I hear you. For what it's worth it is mentioned in the end of the blog post, the project is open source, people can run their own overseer API and create less strict or more strict whitelists, instances can also be registered to multiple chains. Don't mistake my enthousiasm for self run open social media platforms for trying to promote a single tool as the the be-all and end-all solution. Under the swiss cheese security model/idea, this could be another tool in the toolbox to curb the annoyance to a point where spam or bots become less effective. Edit: *The be-all and end-all *not be and end all solution
Obviously biased, but I'm really concerned this will lead to it becoming infeasible to self-host with working federation and result in further centralization of the network.
Mastodon has a ton more users and I'm not aware of that having to resort to IRC-style federation whitelists.
I'm wondering if this is just another instance of kbin/lemmy moderation tools being insufficient for the task and if that needs to be fixed before considering breaking federation for small/individual instances.
He explained it already. It looks for a ratio of number of users to posts. If your "small" instance has 5000 users and 2 posts, it would probably assume a lot of those users would be spam bots. If your instance has 2 users and 3 posts, it would assume your users are real. There's a ratio, and the admin of each server that utilizes it can control the level at which it assumes a server is overrun by spam accounts.
