Is there a way to automate community discovery across the federation?

I started my own lemmy but I’m finding I have to search for and subscribe manually for them to appear. Right now I’m the only person on my lemmy so its gonna be slow going till I grow my community.

Is there an automated way to do this?

Also, are there any good bot scripts for lemmy? I want to get some bots set up to create some daily posts automatically.
