What's a widely used term for a (small) group of users voting up each other's questions / answers/ comments?
Does Stack Overflow have any tools/rules in place to prevent this? Say for instance maximum amount of rep from one user to another? I've seen the FAQ, and it only discusses per day maximums.
I did do a search as my assumption is that this would've been discussed before - but I can't think of a search term other than 'cartel', which yields no results.
