This does bother me.

Maybe they should limit the number of chances, per person, per day or week.

Because anybody who has the time or inclination to do huge numbers of edits is likely to be somewhat of a nut (in my view). At the very least, they're not participating in a profession - something I'd expect from an educated/informed source.

Sadly, I have to say that the wikipedia model has serious limitations.
