The reason people are upset about it is because some of the members of this forum can afford very expensive watches, and many other members cannot, so they make due with what they can afford. When someone comes strolling in trying to pretend he is one of the former, instead of the latter, it pisses people off.
Also, like I said before in different words, fake watches are for douchebags.
That guy probably created a new account and started over after getting ripped on. The joys of forums is you can come in, fuck up, and then start over and no one will ever know.
