Obviously.
There is one fundamental problem of flattr, and all other systems that are based on some kind of popularity measure, [...].

I'm afraid this is not an inherent problem of flattr, or "democratic" elections, or any other manmade distribution system... no matter how technically perfect we design those systems, if some psychologic urge drives us towards twisting any instrument we can in order to obtain advantages in Darwins survival of the fittest race... what can be perverted will be perverted, factly, apparently, stealthily,... or brazenly if force is available.

Better count on it unless you happen to find a cure for Adam biting the apple and its consequences.
