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)

@ariadne tbh, the openness of the MRF subsystem itself is worth a mention here. among the larger pleroma instances there's a culture of if you want some custom moderation feature, you can write a MRF policy yourself and just add it to your instance. I haven't seen anything like that among the mastodon instances (yes, there's patched codebases, but nothing intentionally made to be expandable)

@lillian yep that's because i designed it that way. you can't enumerate all possible threats, so you need a framework that can be extended by anyone.
