things i would like to see in mastodon that pleroma has been able to do for years:

- the ability to defederate an instance except for *explicitly approved* accounts (pleroma has supported this since the beginning of MRF in 2018)

- the ability to defederate a hashtag (pleroma has supported this since 2019)

- the ability to quarantine unknown instances until they are approved by the admin (pleroma has supported this through a combination of multiple features since 2019)
