"The reasons for being anonymous are either good or evil, but usually a fear of evil."

Once again the assumption that this is something to do with "anonymity" - but posting without a label of any kind is nothing to do with merely wanting to be anonymous. You can be just as anonymous by posting as, for example, "GUEST,humph" (" i use different nom-de-plume at different times BECAUSE i want to remain anonymous.") as by posting as "GUEST".

I don't know why nameless GUESTs do it. Some obviously do it to get up the nose of people who don't like the practice ("Looks like some of you fellas were panting around this thread, waiting to pounce.), and there may be other reasons - but it sure as hell isn't anything to do with merely wishing to be anonymous.
