Sometimes, when reviewing certain threads (for example, 'Suggested edits') I notice that there are series of edits from user (usually, low-rep.) with very minor changes. It's obvious that it is an attempt to increase reputation with such kind of edits - and it's not difficult to reject with
too minor reason for me.
But I think such edits are not useful for SO (and, as an addition, this causes load to reviewers) - and, therefore, it will be useful to restrict users from suggesting edits for certain period if they have too many rejected edits already (for example, If user has 10 rejected edits today, next edit he would be able to suggest only after 24 hours)
Should we have such functionality? Same is to other review threads, I think. Something similar is discussed here - but it's different in my opinion.
Edit Here is very similar discussion - my point is still different, may be - because I think automatic restriction (not only mod. involvement) will be quicker. Or may be such functionality already exists?
