I want to create a new ~chan type board but I want it to have some kind of password for posting, like you answer a question before you can post. For example:
Name:___________
Link:___________
Real name of Jack Sparrow?:___________
Etc.
Is this possible?
Yes, but you'd probably have to modify the imageboard script you're using on your own.
Why would you want to do this, though?
If it's to verify that it's a human visitor and not a spam bot, I'd say wait until you actually start getting a decent amount of spam. Adding extra steps to posting is not really fun for your users.
Question/answer things like that aren't very effective either, unless you have a HUGE load of questions. You can very easily make a script that grabs the question and looks up the answer in a local table. Image-based captchas take some skill to decode and it's generally speaking not really worth doing so, so they're more effective in the long run.
But honestly, most spambots are pretty damn stupid. Wakaba's spamtrap fields are extremely effective at weeding out the junk -- I added a log to the spam filter, and it kills about 20 messages a week. The only time I have to delete spam is when people post it by hand, and a captcha or question won't help anything in that case.
tl;dr: don't bother
captchas are extremely easy to get around. especially if you offer people porn to solve them for you.
Except nobody's doing that. Cory Doctrow once suggested that as a theoretical way to get around them, and ever since, people have talked as if that was actually happening. It's a myth.

i tried it once, except with out the pr0n.
i got about 200 captchas solved correctly (and about 50 incorrectly) the first day, 51/9 the second day, and 7/0 the third day... and that's just from mentioning the url once on one irc channel... it'd probably work better if people got something better than a page that just said "lol internet" after solving the captcha... or if i posted the url on 4chan and told them that the script was using the captchas to flood a furry imageboard with random images from google image search (it wasn't, but /b/tards are probably dumb enough to just keep solving captchas without any proof that it's actually doing what you tell them it's doing)...
hi there, I'm not trying to prevent spam, but a certain group of people. I've read somewhere that in 2ch.net, people all over the world can read the BBS but only people in japan can post. I don't know if that's still true, but that's what I want to do except that i don't want to prevent people from posting based on geography but based on a certain criteria.
