What is the difference between removing and purging a community? (lemmy.crimedad.work)

I let a bot subscribe to a bunch of communities on my instance and I think it has caused it to really slow down. Trying to prune what I can. Will removing or purging help? If so, which is best? Is there a way to do it in bulk?

If you remove, the community will remain in your database and this action will federate that you removed it. It will take up storage space.

If you purge, all data about that community gets wiped.

I believe your best choice here is to purge, as that only happens on your home instance and has no impact on other instances.
