Clubs with policies like Fabric exist in other cities as well, to me they are usually a sign of a good club.
Berlin clubs, at least the ones worthy going to, have the same policy of no photos, and heavily enforce it.
I've seen quite a few people booted out from sticking their phone for a picture twice, it's one of the things that can really put a sour feeling on a dance floor. If I'm there to be free and dance my heart out the last thing I want is to be conscious of perhaps getting filmed while doing so. Personally I have politely asked many people to not even try that in those clubs.
I've seen the same policy in some clubs in Amsterdam, Rotterdam, Madrid, Barcelona, Rome, Paris, Brussels, Vienna, and the list goes on. If you can manage to go clubbing at places that enforce such policies I'd say you're 80-90% there on finding a good dance floor.
