Lately, there have been quite a lot of one-time poster, single-post-spammer etc appearing in the forum.
It is pretty easy to see whether these people really are intending to stay and discuss about Geek stuff or pure evidence of spammer. 4 posts that I have seen so far are from single-post-spammer with nothing more to say other than looking for developer or checking out a cheap deal at xyz site or so and so.
I think it is time that Geekzone needs to beef up the security a bit, or putting more restriction to the newbie.
Perhaps implement CAPTCHA to interrupt those quick registration and post. And may even extend CAPTCHA to cover create/reply/edit of new posts and comments. just to help reducing quick-posting. Sure it will turn out to be pretty hassle on all other members but i think it will be pretty well accepted. At least that may help reducing the number of spam posts.
Or perhaps the new members will have very limited access to the forum, until they can identify themselves and their intention with the admin/moderators. This way, they will get "ok, welcome" induction, or a "boot-off-they-go".
Or just more moderators. (LOL)
