The best way to mitigate WAS to use the back up file option. The site i used months ago was Nostrify and it let you save a back up of your follows as well as all your events.

They have since migrated to nostrsync.live but no longer have that feature that i remember for follows, so its just a back up file for events now.

This is another good tool I discovered today and was recommended by others: https://heguro.github.io/nostr-following-list-util/

here is one more: https://metadata.nostr.com/

These ones will take the existing data from browser database and rebroadcast it, so for it to work you have to visit somewhat regularly.
