Facebook knows I'm male, and I see things like this very rarely -- on the order of one or two a month. Maybe that's FB ('s algorithm) testing my "defenses": they/it show me something like that as an experiment, and if I ever clicked on it, the floodgates would open.

But I don't, so it doesn't. Or maybe FB knows I'm happily married and that won't work on me in the first place.

Or maybe FB knows I'm a sucker for chess and go puzzles, so they're my equivalent of this?
