I dont think there is anything wrong with it at all. Everyone has that opportunity to post their photos so that is entirely up to them if they want to or not. Just because some people aren't posting theirs does not mean to say that they aren't considered beautiful or they are being made inferior by others. Its their choice. Some people aren't comfortable enough doing that and some others do. The key there is confidence and appreciation. And if others compliment beautiful people, well, it can very well make their day, so why not. Everyone is posting decently naman and they're having fun and they are doing so at their own expense, not anyone else's. Either you take it or leave it but i have no right to spoil anyone's day. That's my frank honest opinion.
