If you can code in Perl, try the Net::DNSBLLookup module which "queries the major Open Proxy DNS Blocklists, including Sorbs, Easynet, NJABL, DSBL, Blitzed, CBL and PSBL." However, these BL's do not list web-based anonymous proxies. Here is some code to start you off:

use Net::DNSBLLookup;
my $dnsbl = Net::DNSBLLookup->new(timeout => 5);
my $res = $dnsbl->lookup('127.0.0.1');
