How can I report a specific bad user?
From time to time we encounter situations on SO or any of the other SE sites where we expect foul play*. Two users seem far too much involved in asking, answering and accepting each other's questions. Or perhaps the questions of one banned user seem surprisingly similar to those of another new user.
Whatever the case, we all have the ability to flag their contributions and inform moderators that we suspect foul play.
Here on Meta SO however, from time to time a question is asked, I assume for reassurance of the OP that what he considers to be odd is seen in the same light by his peers. While I can understand the desire to do so up to a point, I personally think this is unnecessary. Your efforts are surely appreciated and your concerns taken seriously, but what does a public discussion add?
After all, what can we as regular users do about it? Moderators (from what I know) have far more tools at their disposal to investigate foul play and actually take action in case of confirmation. So a flag should be enough.
And there is another problem in the public calling out of your suspicions. What if you're wrong? Just because it looks suspicious does not mean there really is a problem. The users might be related, but actually provide fair and reasonable contributions. All the while having their contributions negatively evaluated because of a gut feeling. Most of you will at least have seen one case of gut-feeling downvotes where the content of the contribution itself did not necessarily warrant it.
This leads me to ask:
Is there any benefit in such a public discussion that I'm missing? Should we perhaps discourage and close these discussions?
