Ban VPN-Gate IPs on my server

[agazerboy]

I have a chat-server. Many users spam on chat-rooms. To block bad users I blocked many networks such as "TOR" nodes. TOR is pretty good at explaining how to block its IPs.

Many "bad" users now are using "VPN Gate" to change their IPs. I didn't find any valid information how to block VPN Gate network or IPs. Is there a way to ban "VPN Gate" IPs on my server?

One way I can think of is to parse their webpage (http://www.vpngate.net/en/volunteer_servers.aspx) of ips, extract all the IPs and ban them on my chat-server. However, these are all volunteer IPs so everyday there would be new IPs be added. If I parse your pages using cronjob, you might block my server IP for many requests.

Is there any CSV file or XML file with all volunteer servers' IPs? So, I can put all those IPs in ban list?

Edit: a quick and (very) dirty python-script for extracting the IPs.
It create a "ips.txt" file, just containing the IPs (one per line)

qupfer, thanks. However, this list does not contain all the active servers' IP list. This is dynamic list generated by VPN gate. The link, I provided in the question contains all the ips list. Any other idea? Solution?

This board is not for discussing about VPN Gate.

Anyway VPN Gate is designed to avoid censorship.
Of course, the way to acquire a whole list of servers isn't provided.
