block list

A block list is a list of accounts that a user has blocked on a service or site.
Why
You should keep a block list so you can automatically reject spam or otherwise abusive webmentions.
How to
dobrado checks a block list when receiving webmentions. It currently confirms with the sender that the webmention was received, but then discards the mention and logs the request as coming from a blocked domain. (It may be more appropriate to tell the sender that they have been blocked?)

- Example of shared blocklist: https://blocktogether.org/ and criticism, it can and has been (unintentionally?) abused by those with more power (privilege? e.g. celebrity status) to block those with much less power across a wide swath of “subscribers” to those shared block lists.

- criticism of shared blocklists: they can cause damage (disconnecting networks, instances) rapidly, with little recourse and much burden placed upon those added to lists: https://mastodon.social/@irenes/111059965974863510
- "@aphyr we've been publicly expressing concern about shared blocklists for, wow, almost ten years now. we agree in principle that sharing moderation decisions in some form is important, but it's incredibly risky because of how fast the damage happens and how little recourse there is" @irenes September 13, 2023
