There's nothing for lemmy.world because web crawlers like the one at lemmyverse.net (where the bot gets its data from) can't read it.
I think this is due to the 0.18.3 update, and how instances have/haven't implemented the changed to the API
This comment from [email protected] seemed relevant:
This is the same reason I had to turn off my search engines crawler.
There were changes made to the API to ignore any page > 99. So if you ask for page 100 or page 1_000_000_000 you get the first page again. This would cause my crawler to never end in fetching “new” posts.
lemm.ee on the other hand made a similar change but anything over 99 returns an empty response. lemm.ee also flat out ignores sort=Old, always returning an empty array.
Both of these servers did it for I assume the same reason. Using a high page number significantly increases the response time. It used to be (before they blocked pages over 99) that responses could take over 8-10 seconds! But asking for a low page number would return in 300ms or less. So because it’s a lot harder to optimize the existing queries, and maybe not possible, for now the problematic APIs were just disabled.
lemmy.ml isn't currently letting people create communities on it, to encourage users to create communities on other instances and spread things out a bit.
