Personally, regarding my reply, I don’t see how showing my real name would make my review more believable. Future students will anyway just see a name and done, it doesn’t mean anything to them...the name is not more believable than a nickname.
I already told everything to ACC when I was there as a student so they already had the chance to explain the reason of their actions but they didn’t. Also a true potential student would reply or message to ask details about why we don’t suggest the school, while here you appeared complaining that I should expose myself so that you know who I am...why does it look to me that you are working in that school and trying to find out who I am? Because I don’t think that an “A320 captain based in Venice” would be interested in me exposing myself on FB to post a review.
