Device fingerprinting?

Any discussion or thought on device fingerprinting for Lichess? It would enable faster identification, classification and monitoring of cheaters, serial trolls, sock-puppets and antisocial individuals. All with responsible moderators calling the shots of course.

We prefer not to discuss security measures on the public forum. Doing so basically puts a target on our back for hackers and trolls.

You're welcome to come to the #lichess IRC channel and discuss your ideas: http://en.lichess.org/irc
