Welcome the Real World.
Thankfully I had enough street smarts not to fall for this. Unfortunately, plenty did so some bad people got very rich.
Ladies and gentlemen: the Mob. Now in internet form!
A couple of years ago the wise-guys vacuumed up all the juicy content, (steakandcheese, consumptionjunction, etc.) placed it behind traps like this and waited. You followed. They got rich, you got butthurt.
It sucks, yes but you have to have been pretty dense not to see this happening a long time ago; somebody figuring the social misfits of the internet made perfect marks.
Anybody asking for your credit card information should be a dead giveaway that all is not kosher.
