I'm referencing what these three users are doing:

http://stackoverflow.com/questions/36954611/java-line-spaces-concept-related-to-comma-separated-string

See their profiles, they're answering each other's questions and giving upvotes. I've flagged this for moderator attention (we'll see what happens), but generally, what is the best way to handle stuff like this?

I can totally see it possibly being ignored by a moderator (due to all the other/more important work they have and the fact that those questions/answers can indeed look legit - which is something the posters would go for if they were any smarter) and stuff like this will generate tons of bad content on SO.

Should we have a way to flag users, not just answers and questions?
