If their IPs became known, they might get blocked?
if people are rotating IPs to dodge your blockers, maybe you could shadow-ban them instead? that way they don't know that the IP is bad.
Most users are on dynamic IPs. So you'd probably be blocking/nagging the wrong person
Lots of sites (e.g. Stack Overflow) block IP ranges of cloud providers.
Just be sure it's not an ip that many legit users are passing through ... Like in the days when dial up aol users would all pass through the same IP.
You'd be better off banning known "cloud" IP ranges than this (and I think even that protection is questionable).
Why didn't their upstream provider just blackhole their IP ranges?
They don't use anything sophisticated, it's just IP range blacklist. Hint: try different VPS provider, there's plenty out there...
Until ISPs and the backbone connections start banning the IP addresses
Why couldn't there be a crowdsourced list of ips to block similar to adblocker? You could set flags of IPs to block based on your preferences
