What about people like me who host an instance just for themselves, but don't have any communities in their own instance? What's the risk for me for getting blacklisted? I didn't find an clear answer by looking at the source code.

You have one user and has many comments and post as you make yourself. This means that your suspicion score is going to be extremely low (under .5 if you post 2 times on any server).
Thank you for trying to get ahead of the spam influx. Trying to beat the spambots is a thankless task, but thank you anyhouw.
A funny result is the accumulation around server centers, here Hetzner.
Excellent! Thank you for doing this!
That's a cool idea. Thanks for your work!
One question: Let's say the script defederates an instance and then the admin of that instance cleans up their database and makes sure no new bots can register. Would your script remove them from the blacklist or would I have to manually check if all instances on my blacklist are still "infested" to give them a second chance?
If you run my script in a schedule it should remove them from the defederation list yes
Oh, now I see it at the end of your post: "... any servers that cleared up their spam accounts will be recovered." Totally missed that. My bad, sorry.
“Lemmy Overseer “ is a creepy, ominous name. It sounds like the job title of some super strict, rules-obsessed, joyless office drone who works for the feds or a large corporation.
This kind of talk really displeases the Overseer. You better watch yourself.
yeah it's great isn't it‽
maybe that's a dumb question, so sorry for that, but wouldn't it be easier to just use a whitelist for federation instead of a blocklist?
That would lead to having to manually approve every instance by the admins. Mods can't do that so it would 100% be on them to keep up with all the instances
Thanks for the awesome work! I love seeing the OSS community building tooling for this stuff :D
However it does not look like it is open source.
Isn't it? I had to go to the Python script and go up to find the main repo https://github.com/db0/lemmy-overseer
It's also possible I'm missing something lol
Maybe I'm being stupid, but how does this service actually determine suspicious-ness of instances?
If I self-host an instance, what are my chances of getting listed on here and then unilaterally blocked simply because I have a low active user count or something?
Important question; author kind of answers here:

If I were to rely on this for my instance, I would require that it be completely transparent and open source. It doesn't look like this is; you have to trust that it is making good selections, and give it power over your federation status. It's a dangerous tool, IMO, but I can understand why it would have appeal right now.

Are you sure? Kinda seems like it is.
"The Lemmy Overseer" as I understand it is a backend service that gives us an API to use.
There is an open-source script for interacting with it. However, it does not tell you how that backend service works, exactly. It's a black box with well defined interfaces, best case, as I understand it.
It's based on dynamic count. For now it's a very simple how many users per post there are and each instance can set their own threshold for it.
It's not about few users, it's about a tons of users and no activity. If you have 5000 users and 3 posts, it's likely those are all spam accounts. This is what we're checking for right now.
This is not a manual process currently, but I'm planning to add the possibility to whitelist and blacklist instances manually in the future.
Looks like a very cool project, thanks for building it and sharing!
Based on the formula you mentioned here, it sounds like an instance with one user who has posted at least one comment will have a maximum score of 1. Presumably the threshold would usually be set to greater than 1, to catch instances with lots of accounts that have never commented.
This has given me another thought though: could spammers not just create one instance per spam account? If you own something like blah.xyz, you could in theory create ephemeral spam instances on subdomains and blast content out using those (e.g. spamuser@esgdf.blah.xyz, spamuser@ttraf.blah.xyz, etc.)
Spam management on the Fediverse is sure to become an interesting issue. I wonder how practical the instance blocking approach will be - I think eventually we'll need some kind of portable "user trustedness" score.
yes, constantly adding new domains and spamming with them is a probably vector, but I'm not quite sure if that works due to how federation works. I am not quite that familiar with the implementations.
