@Facebook @Twitter You jest, but while it can never die due to OSS, I imagine it would be rather easy to subdue instances the same way big companies always subdue small ones...exhaust their resources. In this case, that would just meaning creating bots to create accounts and spam instances continually until the sysadmin gives up or runs out of money... :-( Of course if any large company was ever caught doing such a thing, they'd have hung themselves...
