@thor i've chosen the amsterdam exit as the ping was shorter than to frankfurt :)

i think the blocklists consist of looking up which ip ranges are owned by VPN (or anything not considered end-user) companies and then block them, regardless of which country they are in.

it's the same for mail servers, there are less and less ips which you can use to reliably send mail from. which is totally bullshit, 99% of the blocks my rspamd does is not because of some ip range shit, but because it's really obviously spam detected by the bayesian filter or the headers are fucked up.
