I know that "profiling" is no longer politically correct, but stopping a person crawling out of a back alley window carrying a TV with a cut power cord, is not "profiling" as far as I am concerned.

As a long time member of various boards and an administrator, I'll agree with Dean Roddey -- this is a spammer. Typically, the spammer will post vaguely worded, inappropriate text for a few posts in an effort to end run the forum's "nanny" (preventing image posting and links for new members). After the nanny backs off, the spammer will change the signature, and/or edit all of the older posts in order to inject the message. Some spammers will register and remain dormant for a year or more. Often, the originating IP address is a big clue and the administrator can avoid a lot of grief by blocking certain IP addresses.
