Sites are often dynamic, and it would take a hell of a lot of log grepping to stick a site to a specific player... particularly if said player uses one of the big providers.

That doesn't even get into the complications that are routing. I for one often appear as if I'm from WI, MI, Ohio, New York, PA... And I'm not even in the States.

So that leaves... What? Equipment tells? The container they prefer for water? Post and cross character interests?

Are ya'll the NSA with huge dossiers on each site that connects and plays a character over 50 hours?

The only other way I could even BEGIN to imagine is that you get the information via word of mouth and guess work. Which in many cases is going to be totally wrong. I've often heard that various people think my characters are the following: Torak. Graatch. Pro. Rogue.

I'm none of those players, and to my knowledge, never have been. Also wasn't Ieralaine, despite my record of playing less than stellar good characters.
