I have always had mixed feelings about OS untill I saw something that really disturbed me. Someone had a bunch of wedding pics up and on the guest page a person- Presumably male, posted “hey, I dont know you and i am using s/o elses screen name to post but whose that georgeous girl in picture #x”- I am not joking!! then, in that picture he inserted himself using one of the features where a box encircles a face in a picture and has that persons name at the bottom. in this case, he didnt put a picture of himself, rather just the box w / the “fake” sign in name he was using, as though he was “standing” next to her.
Even if it was a joke, the whole thing was extremely distasteful and bordered on being crass.
