Cell Phones Banned From Gyms

Many gyms have a no cell phone policy in place when it comes to group fitness and locker rooms, but what about the whole gym?   After some research it looks like the only big chain I have found that has a policy like that is Planet Fitness. It's tempting enough for me to want to join!  But its not just the chatter of other people that bothers me as it is these horrible video clips of people working out.  Typically they are doing it wrong, look awkward, making faces or something that is comical to the person recording.  I always wonder what the person behind the camera/phone looks like.  My guess is they are wanting to improve something.  And they probably would if they would put their damn phone down and do their own work instead of worrying about what someone else is doing. 
I really don't get those videos.  I mean, you see someone doing something wrong or even potentially dangerous.  Are they corrected?  NO!  They get recorded and it's blasted all over the internet.  I can't be the only  one who see's this as a major issue?  Why to people go to the gym?  To get healthier, improve confidence, get stronger, be happier.  When they see a video posted that is laughing at them, how hurt and ashamed they must feel.  What I don't understand is, why doesn't the person with the phone, put the damn thing down and go talk to the poor soul doing the wrong moves?  Correct him/her.  Show him/her how to do the moves properly.  And if they have no desire to do that, then put down the damn phone and concentrate on their own work out! 
This whole thing got prompted tonight when someone posted a video of a guy doing the wrong moves.  Long story short, it ended up an online debat - no name calling - but was still frustrating.  Some people posted assumptions about the man based on what he was wearing and commenting that "guys don't want to be helped by someone who isn't bigger or stronger..."  blah blah blah.  This poor man was recorded on 3 separate occasions.  I say this again, the man behind the camera should put down his damn phone and pay attention to the work out he SHOULD be doing instead of the way another man is doing it.  It all seems childish and such a waste of time.  And really - it downright pisses me off.  That man is being bullied.  I know people are tired of hearing the bullied card but what else can you call it?  It gets turned into a cyber bully thing. 
Or maybe I'm just to damned caring?  I see posts like that and my heart actually breaks for that man.  Here he was, trying to better himself, and some jockhead was recording him so all the muscled people on the internet could laugh and point.  Way to go asshole
