Satoshi
left this place a long time ago, thanks, partially, to you & your ilk.
He has not "chosen the admins carefully" any more than Lenin has carefully chosen Stalin. If you have evidence to the contrary, please present it.
He also did not create this forum in hopes of, someday, getting awesome Alexa ratings by attracting all of the internet's petty thieving lowlifes, thus supporting the mainstream conception of Bitcoin as the currency of greedy but otherwise laughably inept criminals, and degenerate gamblers.
You'll have to just take my word on that one

Satoshi left before any service was started being promoted, so its not because of the "spam". Admins are good, the forum is supposed to represent all the areas of Bitcoin, which can be seen in Boards and sub-boards, and its just that Gambling happens to be a big part of Bitcoin, believe it or not.
Scams are discouraged due to the "invention" of Trust system, which cannot be abused by any random newbie with lots of alts. And as I said before, Caveat Emptor, look out for yourselves and don't blame the admins for anything that happens.
