Can stackoverflow detect collusion?
For example I have seen 2 programmers collude when one of them already has a predefined question with the predefined answer. The other programmer already knows the answer so as soon as the question is posted the other programmer immediately provides the correct answer and is the hero of the day.
Should stackoverflow detect and take the appropriated actions? Or does the principle of crowd-sourcing make collusion negligible.
How does stackoverflow detect this? I suppose it can check the amount of questions and answers between 2 users, and if it is above a certain threshold, they are flagged?
What actions would stackoverflow take when collusion is detected?
