A place to post new communities all over Lemmy for discovery and promotion.
Rules
The rules for behavior are a straight carry over of Mastodon.World's rules. You can click the link but we've reposted them here in brief, as a guideline. We will continue to use the Mastodon.World rules as the master list. Over all, be nice to each other and remember this isn't a community built around debate. For the rules about formatting your posts, scroll down to number 2.
1. Follow the rules of Mastodon.world, which can be found here.
A. Provide an inclusive and supportive environment. This means if it isn't rulebreaking and we can't be supportive to them then we probably shouldn't engage.
B. No illegal content.
C. Use content warnings where appropriate. This means mark your submissions NSFW if need be.
D. No uncivil behavior. This includes, but is not limited to: Name Calling; Bullying; Trolling; Disruptive Commenting; or Personal Criticisms.
E. No Harrassment. As an example in relation to Transgender people this includes, deadnaming, misgendering, and promotion of conversion therapy. Similarly Misogyny, Misandry, and Racism are also banned here.
2. Include a community title and description in your post title. - A following example of this would be New Communities - A place to post new communities all over Lemmy for discovery and promotion.
3. Follow the formatting. - The formatting as included below is important for people getting universal links across Lemmy as easily as possible.
Formatting
Please include this following format in your post:
[link text](/c/community@instance.com)
This provides a link that should work across instances, but in some cases it won't
You should also include either:
or instance.com/c/community
FAQ:
Q: Why do I get a 404?
A: At least one user in an instance needs to search for a community before it gets fetched. Searching for the community will bring it into the instance and it will fetch a few of the most recent posts without comments. If a user is subscribed to a community, then all of the future posts and interactions are now in-sync.
Q: When I try to create a post, the circle just spins forever. Why is that?
A: This is a current known issue with large communities. Sometimes it does get posted, but just continues spinning, but sometimes it doesn't get posted and continues spinning. If it doesn't actually get posted, the best thing to do is try later. However, only some people seem to be having this problem at the moment.

MODERATORS
Thanks you, I'm personally more interested on the statistics used on the parameter searching, but given that is python I'm checking out to see what can I learn.
I added an explanation of the details of how it works to the source file that implements the main rank algorithm. The math behind it is not simple, but it's also not rocket science, if you have some data science abilities and want to check it out.
Don't let the python fool you. It is not simple python. I'll try to add some comments later on to make it more clear what's going on.
For tuning parameters, it was complicated. Mostly, I did spot-checks on random users at different ranking levels, to try to check that the boundary for banning matched up pretty well with what I thought was the boundary of an acceptable level of jerkishness. That, combined with deeper dives into which comments had made what contributions to the user's overall rankings. And then talking with existing moderators, looking over the banlists, and bringing up users where they thought the bot was getting it wrong. There were a lot of corner cases and fixes to the parameters to fix the corner cases. Sometimes it was increasing SMOOTHING_FACTOR to make users more equal in rank with each other, when we found some user that was banned because of one bad interaction with some high-rank person who downvoted them. Sometimes it was changing parameters to change how easy it is to overcome a few negatively-ranked postings by being generally positive with the rest of your postings. There are always users for which the right answer is a matter for debate or opinion, but as long as the bot isn't making decisions that are clearly wrong, I think it's doing pretty well.
You can look over some places where I talked with people about the bot's opinion of their user, in this post and this post. I don't want to publicly do those breakdowns for people who haven't agreed to have it done to them, but that might give you an idea of how the tuning went. What I did to tune the parameters was the same type of thing as I showed in those comments, just a whole lot more of it.
