At this point there are 32 posts to this thread, including this one. Fifteen of those are from GUESTS, and 11 of those are GUEST + a pseudonym; no problem at all with that. And I've yet to come across anyone being hostile to people who do that. (Well, not for posting as GUEST + pseudonym anyway.)

However four of them are just GUEST, without any kind of handle, not even a number, and the problem there is that there is no way of knowing whether this is the same one posting four times, or four different ones or whatever. When you want to make some comment on what someone has said, it is bloody inconvenient having to say for example "As GUEST 09-Apr-02 - 01:20 PM said..." And it's inconvenient for the people reading it as well.

Deliberately causing inconvenience to other people for no good reason is a very unfriendly thing to do. And it also messes up the process of communication, and that is unfriendly too. Unfriendliness provokes unfriendliness in response.
