Max, forgive me for raising a slightly paranoid point, but I have been dealing with a "nasty" in another situation entirely, which has warped my interpretations briefly. I can see that you may have ways of identifying a problem poster under an alternative name, but suppose the posting is made under the guise of a member in good odour? Can you tell when I post as a member, with the cookie operating from when I post from the other profile on this computer, without it? Or from the Internet cafe down the road? Or it isn't me at all, and from somewhere completely different?
