Thread: Catch dupe accounts made through public proxy servers

We would need a script that checks every connection from a newly registered user and performs a tor DNS lookup, to find out if it was a tor exit point. Tor is a widely used anonymizer so this method would catch a lot of them.

There's also another method.

If you try to download from a tracker through a proxy you will always be listed as an "unconnectable" client because the tracker will be unable to check that you're capable of accepting incoming connections. I just know there is a back door entrance to this one if you eliminate the variable of actually being unconnectable (there are ways of fixing unconnectability by forwarding your router IP or adding an exception for utorrent) but I can't find it

Quoted that from my post in another thread.
The second method would require a base of a tracker and a team to check and fix unconnectability. I can't see any other way.

Anyway, both methods would require programming experience, something I can't help with because my knowledge ends here :P

This wouldn't prove that it's a dupe.
I used to use Tor/proxy/vpn's all the time.
I've never made a dupe account.
Good idea, but it wouldnt work.

I can't see any reason to use a proxy on a forum

The problem is, no matter how to try to detect it, people will still make dupe accounts. They'll find proxies you haven't banned, change their IP address, make the account from a public computer or unencrypted wireless, or use a friend's computer.

There are tons of ways around ip based bans. The only way to really ban people is to have them confirm their identity, which is challenging and very time consuming, so pretty much nobody does that.

I didn't say it will catch all of them but most. At least it will give them a hard time lol
