It's not good in general to lose freepers. But I make an exception for myself. Here, like everywhere else, I am pretty much expendible. Also I'm just one person so who cares. But couple of freepers were lost because they invested way too much of their effort into "proving" that a certain document was a forgery. Polarik was one, I don't rememeber any others.
But they were demonstrably, painfully and pathetically wrong. And I was right. But who cares. Only people like you apparently.
