With the rise of phone cameras, you really do have to think twice about throwing caution to the wind these days

True. Fortunately, this club has one rule essentially. No photos and vids. If one get caught, he/she is immediately removed from the club, while photos are deleted (yes, one has to hand over the phone to the guards). Plus, the person is blacklisted, no entry anymore, for at least a year, and when photos of little dressed or naked people are taken, I can imagine a ban for life. Profile photo is put on a board at the entrance, scanned by the doormen. I guess it works, since it is mighty difficult to find any photos on the internet, while the club's existence is in the decades.

As became practise years ago, cameras get a sticker upon entry. This drove other clubs to do the same, for different reason though (being in the clubs, dancing and all that, shall be in the here and now, not through phone chats and social media).
