While reading posts on slate.com I was struck how many were "noisy" and similar to past posts I've encountered. Certain memes pop up repeatedly (usually denigrating someone) and contain no useful information. It occurred to me there might be a websites or analysis tool or a service that would indicate which posts were likely to have been generated by a robot.There's probably a vocabulary and an entire work milieu/domain/subject area about this topic but I am naive. Can anyone help me here?
