No issue with guys being hidden, but the 1 way aspect is irritating. We should be able to not allow hidden profiles to view us. We can only block them if they message us, but they get to repeatedly look at our profiles, wink, etc. It's just tedious. Let them be hidden (no issue there), but if they're just browsers/stalkers it facilitates the worst aspect of this site.
Hidden profiles are a nuisance. I hide mine if I go on holidays but if my profile is hidden I'm not contacting people.
What I like about blocking them is that you can see their profile pic, basic details.
