This would be nice to see.

How about using a captcha ?

A captcha only works (if you're lucky) for automated spam and not for spam (as I believe most of ours is) where humans are involved. It also radically impairs the user experience.

Another possibility could be a sort of edit-count-barrier for new users (let's say 10 edits) after which they are allowed to add something to the diary.

That sort of thing is already taken into account by the spam scoring, which includes the number of edits the user has done as well as an analysis of what they write.

We now have a way to report diary entries (see openstreetmap/openstreetmap-website#1576 ) and various other anti-spam work recently. While it's an ongoing battle, this particular ticket is resolved.
