Im glad i dont use instagram regularly. That is really annoying.I follow the Polene hashtag on Instagram and some people just use the hashtag under every photo, if there is a Polene bag in the photo or not. Probably because it attracts a lot of people. It's very annoying actually.
I even came across a very obviously fake Neuf once, posted by an influencer. I left a comment but I guess it was deleted.
