I propose we change the names of "guests" on our forum to something a bit more nasty, since guests aren't really beneficial to promoting Arlong Park as a popular hub for critical discussion, debate, and social relations over the information superhighway. Guests contribute nothing to AP and instead leech bandwidth, and I am willing to cite them as the primary source of spoilers on other boards. There is, indeed, little incentive to register on this board and I'm not sure if malicious guests (hammerers) are able to be banned.
Hopefully, with a less cordial term labeling these unregistered users, more will be willing to register, which is the first step toward having them contribute to AP.
As to what this term should be…I have no idea. "Fishbait" is the first thematically appropriate term that comes to my mind, but an even more sinister label would be 'weeaboo'.
