I didn't find any other topic like this, so:
Imagine the following scenario:
User A and B (possibly C,D,E...) want to abuse the system like the following.
- A asks some simple question.
- B answers the question correctly (since it's simple and ontopic, i.e. a regular SO question, but possibly a duplicate).
- C,D,E... all upvote the answer of B and the response of A.
If this happens repeatedly, A and/or B can quickly gain a lot of reputation.
Is there some automatic analysis tool that shows the moderators such "clusters" of abusers?
Or are the moderators able to deal with such situations manually?
