Maybe someone enterprising can start a service that automatically posts a bunch of innocuous stuff to a FB profile so I don't have to bother wasting my time with it.
Given that scoring bots in mass use will necessarily decrease the dimensionality of the data into fewer, more tractable features, and thus creating bots need only to target the dimensionality-reduction step, rather than reproduce "human behavior."
Which seems rather simple given the variance in natural language and normal human social interaction.
