ya know what ?

Gonna move on to something else, this was just a test
anyway, a proof of concept attack so to speak.

The best way to stop this is to use those DNSRBLs
you were trying to use. You just need more sources
If I were you, I would also download all the socks4
and 5 IPs like I did...

/usr/bin/curl -# https://raw.githubusercontent.com/TheSpeedX/SOCKS-List/master/socks4.txt -o socks5-1.txt`
/usr/bin/curl -# https://raw.githubusercontent.com/hookzof/socks4_list/master/proxy.txt -o socks5-2.txt`
/usr/bin/curl -# https://github.com/ShiftyTR/Proxy-List/blob/master/socks4.txt -o socks5-2.txt`
e 
There is also more sites that I would grab from

With a little code, I am sure you could make your own DNSBL or just send these to them to add
to their list.

It was good spnaking your server, Paulo. HAND
