I've come across multiple questions from the same user, the last one being this one.
As you can see, it has an extended amount of edits, consisting mainly of adding and removing "..." from a sentence.
This was done as to appear on the top of the question feed (I don't see any other reason), although the question has a bounty on it.
My question is: what can we do to prevent such behaviours? Am I supposed to flag all his questions (because that's clearly what he does every time: 17 posts edited / 744 revisions)?
Looks like he's been using a different strategy to get people's attention, for example here and here, he's just edited the whole question to ask a new one.
I do think that obnoxious behaviour should be delt with once and for all. His questions don't bring anything interesting for the community, he just want his website(s) done by people from Magento SE no matter what. He should hire someone in that case and not spam Magento SE for his work to be done in his place.
UPDATE 2: I don't mean to sound like a crybaby (see what I did there? ;)) but it looks like he didn't get it and still tries to get attention no matter what. I was on StackOverflow looking up at the Magento questions when I stumbled upon this one which looks exactly like this one on Magento SE. Please take action, this is getting ridiculous.
