Profiling

Profiling is the process antis engage in who wish to out those they suspect as being pederasts or pedophiles. They do this by collecting information, over time, on posters.

Posters who participate on chat boards and message boards often are unable to remember exactly what information they have already publicly posted about themselves. Over time, in small increments, they may provide more and more personally identifying information--without realizing that they are doing so. Eventually the "profilers" may collect enough information to "out" the poster.
