One thing I've noticed is the bot seems to "correct" people who include both the Lemmy-friendly link and the actual URL in their post. I've seen this a few times, although it's possible the posters are editing the posts to add this in response to the bot. It'd be nice if the bot could check for this.
Fyi your bot is apparently trying to "correct" people posting from Mastodon too. Seems like it's replying to every comment that comes through from Mastodon's side. Example: https://lemmy.world/post/1628806
If people can’t be arsed enough to even get their post format correct (when it is clearly described in the post rules), they don’t deserve the free promotion.
To be fair, if you can't figure out how the syntax works based on the clear text, and usage everywhere else in Lemmy, you shouldn't be allowed to host a community.
Technically the actual link is /m/newcommunities@lemmy.world, but if your kbin instance has no subscribers to that community yet, you have to first find it with the first link and subscribe to it, otherwise you get a 404.
At least on kglitch.social, using !newcommunities@lemmy.world seems to work like a combination of both: Searching for it when kglitch.social doesn't know about it yet, going to /m/community if kglitch.social does know about it.
