This Kind of Post Brings Up Questions

Here you find a teacher asking whether Yes Youngdo is a good place to work. Then there are other prospective teachers comments, and then a post from a then YY teacher who writes about only good things.

Does it occur to anyone that YY is very likely asking teachers to respond to these posts with good info about working there? And since the prospective teacher is asking about one branch in a certain city, and the current teacher who responded is one who knows about that branch, doesn't it seem likely that management asked this person specifically to post here?

In other posts I found on other sites I saw that teachers said the best way to find out about Yes was to talk to teachers currently working there and that the institute would provide their contact info.

I can't help but wonder while reading these posts why the teachers don't seem to realize that YY would obviously only give out the contact info of teachers who will definitely say positive things -probably those who are close to management or considered the best teachers.
