Totally agreed that email DNSBLs are a failed system; they just become a centralised blocking mechanism or protection racket.

The idea that we're experimenting with in Matrix is instead to let anyone publish a reputation list (greylist), and mix together existing ones, and use it to apply whatever rules they like at whatever granularity they like. In other words: at the account level, let users hide users or rooms they dislike. Or at a community level, let moderators block users based on whatever criteria. Or, worst case, at a server level (although we haven't seen much of that in practice, unlike email or activitypub).

For instance, an obvious capability would be for rep lists to also have rep themselves, so you can gauge whether a given rep source has become corrupted, and switch as needed.

In other words: this is primarily about empowering users, rather than empowering admins, and giving users the tools to block stuff on their own terms and make up their own choices, rather than being beholden to a DNSBL-style cabal, or whatever rules their server admin happens to adhere to.

I love this - and if we can make them easy to fork, easy to post discussions about - I can see them becoming very useful - and different groups of people will use and rep up different ones based on their own criteria.

So it may be useful to have different rep points for things like this - I can see some users voting up ones that follow their religious tribe for example, and others that rep up the blocklists that focus on their left/right tribes, some who don't want the X part of list A but want the Y part of list A and B.

ultimately I wonder how these could be posted for open discussion and ease of forking so the processes can really get going.

If users can easily apply these (and remove / switch them) to their browsers and apps - this can be hugely useful.
