Yeah, but I think that option is mostly used as a way for women to keep men from messaging them so they can message the ones they choose without being constantly harassed by throngs of men they aren't interested in. Not that it works, a lot of men message anyway because they never read the profile in the first place. A better strategy is to identify as homosexual and explain in your initial message that you do that to keep creepers from messaging you. Of course, then you have to let down some actual homosexuals, but I imagine that's a lot smaller pool to filter.
