Guest account for unregistered users?
The recent article about kernel forking, due to its controversial nature, attracted lots of visitors and potential commentators, but unlike before I never enabled, even temporarily, anonymous posting. Hence there was absolutely no spam, which is the whole advantage of allowing only registered users to post.
And even despite that, some have registered and commented, and I wholeheartedly thank them and welcome them to the site.
However, this brought me to an idea. We could, instead of ever enabling anonymous users simply provide an alternative option in form of a guest account. So those who do not want to register, but would rather just post that one comment can simply log in using an universal guest account and be done with it.
The guest account can have limited permissions and would be easy to control. Because of that and because of the fact that bots and spammers would still have to go through the extra trouble of putting the username and password of the guest account in, I think there would barely be any spam through it.. and what there would be it would be easy to detect and delete.
This idea was inspired by a site called bugmenot.com. I could add the guest account to that site's database as well.
