How to check who gave 0 points? [logged]

[werdan]

Dears,

I have a big problem with one my user. He always gives a zero points for each new photo.
I know how to find a login when he is logging during a session but he always enter logged.
Our comments to him don't work. He always do the same.


How to find the nick/login?

Maybe somebody help me.

Enable vote_details in the logging section of the config. This way, you'll be able to spot his IP address. Look up that address in your server access logs.

I forgot to write that I did it. I know his IP address but I'd like to know his login.
His IP address is various. I can't block him accordng his IP.

I can check in server logs what he did.

This guy enter logged into my gallery. He doesn't write comments and upload any images.
Just put zeros for each images.

If he enter to gallery, log in and vote. I can find him but he is always logged.
That's my problem.
