Their pictures were readily on the web. I didn't say anything salacious about them. And to be able to actually find me from these specific posts out of everyone who lived in our dorm or knew the urologist's then girlfriend (and now that I think about it, while I am 100% sure I knew the girlfriend, I'm only 90% sure we lived in the same dorm at one time), well while it might theoretically possible to discover me, it would take spy level movie skills to do it. Now if someone were to take all my posts over the years, or trace my internet connection from my posts, it would be easier. But I'm going to assume, the majority of people who use the Message Center don't have those skills. And for the few who might, why bother? I'm a middle-aged gay male with a failed career who is living on the edge of poverty. What good would it do to out me?
