What is the purpose behind these? Do you suppose badges incentive this sort of behaviour?
As a general case, people should be encouraged to edit posts that they don't find fit. Usually this should be done to format code, correct spelling or grammar, properly tag questions, ...
Magento offers some incentives for this. There are 3 badges for editing questions
In this case I think someone just wants the Gold badge. If you take a look here you will see that that specific user has about 400 edits. I think he's aiming for 500.
I don't want to send him an e-mail to stop because it seams to me like this is a harmless action just so he can take a badge. It brings no value to this website but it doesn't hurt it either. (maybe it just annoys people but he will stop after 100 or so edits more)
In case you are reading this Keyul Shah, please stop editing random posts. If you really want to help and earn your badge, at least find posts with problems and improve them. A lot of people (myself included) will be very thankful if you do it. This way you will feel like you really earned the badge. If you keep editing random posts your badge is worth nothing.
Thats a normal thing in community managed content.
And I think its a good thing to have people making small improvements. In this case most of them are formatting, like missing
code wrapping which can make questions and answers more readable.
Even if it is only for a badge, it offers an increased value to the Site and it doesn't matter how big the improvement is. We need people who go trough all the questions, and if he also does some up/down votes during this, even better.
He is probably one who of the few, who read really a lot of questions during the last weeks.
