Since the "Used by" is some kind of horrible marquee something, I can't readily tell but it looks like your own Discord is not among the used-by list. Is that true?
It's not in the used-by list as that's mainly meant to highlight communities that have a lot of activity as each one should be a good example and there aren't too many questions in my server yet
Thanks for pointing that out! The robots.txt file was in the location, that got messed up a bit in the move over the open source version but is fixed now
For the weekly changefreq on Discord server url, are you arguing that's too frequent or too infrequent? On the server page, it has recently indexed questions so part of the reasoning behind that being weekly is to capture those recently indexed questions https://www.answeroverflow.com/c/143867839282020352
Archived threads get a change freq of monthly since they don't change that often and active threads have a changfreq of daily as there is lots of activity going on in them
