I have seen this post:
BGP Next Hop Blackhole - General questions - VyOS Forums
I have seen this list:
raw.githubusercontent.com/firehol/blocklist-ipsets/master/firehol_level2.netset
And I believe that the best option to block such a big list (I have couple others) is to use a locl or remote bgp peer that will publish the routes.
I was thinking of using exabgp to publish the routes to VyOS or FRR just to test it.
I would be happy to get recommendations on how to implement such a function.
