You could probably find a ton of users that repeat what others are saying, but if you look for it you are just going to drive yourself crazy. I've opened tons of threads and the 1st 10 replies usually have 3 duplicate answers with words slighly different.
I would just report them to their campaign manager and that manager will likely take a deeper look at a user.
Thanks for the suggestion. Please notice that this is just an example I found lately, but as you said the problem is perhaps much larger than it looks.
Alrights folks, since I received an answer to my question, I believe this thread should be locked.
