I'm being hit with 300 req/s 24/7 from hundreds of thousands of unique IP's from residential proxies. I can't rate limit any further without hurting the real users.

Yeah real users are just as hosed as the small sites. I get blocked simply because of the netblock I browse from.

Yeah, IP-based rate limits are nearly ineffective these days.

Nginx has per server, per path limiting options.
