Of course they can tell. Webmasters have eerie powers. And legions of flying monkeys which they'll send out over the Intarweb to track you down and give you such a wedgie.

Not to mention they monkeys' eerie powers. Well, not really eerie; more . . . preternatural. I mean they can fly and give superwedgies, but that's about it. Above and beyond what one would normally expect from monkeys, at least.

Oh, and if you've ever logged in to the site from anywhere you'd better make sure to check the name on your waistband now (because that's how the monkeys check they've got the right guy; if you don't have your name there, they'll take your wallet to first check your ID and give you the aforementioned wedgie).
