people have things they don't want everyone to know. how is wanting a small amount of privacy ridiculous?
"Hey, Jimmy, I went searching for your porn habits and found that you are into fat redheads. Shame on you, shame on you. You are now excommunicated from... Somewhere". How is this not a much bigger social faux pas for the accuser rather than the accused?
And why would want to keep in touch with a coworker that gives a damn about what other people want to fuck? I would go straight to HR for harassment, first of all.
That is not the same as understanding why would anybody care if their porn provider made their porn watching habits public, which is the subject of this thread.
Can you please clarify your reasoning? I fail to see the supposed "gotcha". We are not asking why doesn't everybody make their porn profile public, that's something you came up with.
They might be interested in seducing you.
Otherwise, no reason.
