Sessions would work provided that they don't close and re-open their browser. As soon as they do that the session is gone and they can repost straight away.

Slightly more difficult for them to get around is to capture their IP address and disallow posts from the same IP for the period. Chances of the IP address being reallocated to someone different who then tries to post within that time is probably unlikely.

1/ set a session
2/ set a cookie
3/ log their IP and time

do them all or just pick

How about a database oriented solution? We save the time of last post in the database, when for each new post, the time field of database is refreshed with the new time.

Then, when user tries to do a post, we check the time of the last post from the database. Of course this will work only when user has a log in and password. On the other hand, it will work on computers where cookie is disabled, user can't just post by opening a new window, or by changing their IP address. You are restricting posts per user name. If you want to restrict posts per machine, then IP address might be the way to go.

Having said that, I'll tell that I'll probably never do such a thing. Aim of any community site is to encourage users to be in the site longer, and do more posts, not the contrary. Disallowing user to post with an interval of 15 minutes can seriously discourage a lot of users to come back to the site. Personal opinion, of course.
