This is a very cautionary tale for all devoted denizens of Facebook:
"2 Texas College Students Outed by Facebook Loophole"
Unlike Oasis which is not-for-profit, Facebook is strictly for profit... and you may be assured that any obscure device that will increase their share value will be exploited.
Its rules and policies (particularly those that apply to one's personal information) are inscrutable and constantly evolving.
Don't let this happen to you... unless, of course, you don't really care! :(
btw: In the event you failed to discern this from the article, McCormick and Duncan were not an "item"... they were merely independent UT students who happened to both be gay... and were individually ensnared by just one of FB's many and far-reaching tentacles!
