I have to say, I've experienced the special treatment. I can't help it when someone tosses me items (flippin' character always picks them up automatically) but in survival servers in the past, male players always insisted on having me move in with them. I want to have fun and mingle and whatnot, but sometimes it's just awkward. Once, I somehow I ended up as some guy's "Minecraft wife" even though I didn't even consent to it. It was weird.
But recently, I only ever play with my brother on PVP servers, and my current skin is a naked chicken man with a leaf, so no special treatment here. I've never even tried using a female skin on a PVP server. I know how that community is.
