Bot restrictions?

Hello!

I was wondering if lemmy.world has any bot restrictions / throttling behavior? I have a bot (ported from reddit) that is performing the same activities on lemmy.world and fanaticus.social, but I'm seeing different behavior: on LW posts aren't being featured correctly and comments aren't being added. I'm not seeing any significant configuration differences, and they are running the same code - Is there a server side explanation for this?

If you have any other suggestions for good bot lemmetiquette, I'd definitely like to hear them!
