I just noticed a particular user that has a large amount of throwaway answers. They seem to almost always take the form:
This may be of help [or another generic phrase]:
And thats it. At first I thought it was a straightup bot. But some answers vary enough that he's at least partly human. Is it possible this guy has some kind of script running that could do this (I know nothing about such things) or is he just a serial google-copy-paster?
I can id the user if needed but don't want to make a stink if its no big deal.
EDIT: Okay, this is the user: http://stackoverflow.com/users/827603/karan-shah. On further inspection, he is most likely not a bot. There is just a very set pattern in his answers, such as the frequent signing of his name under the posts despite people editing it out. I agree with the responses to this question, nothing about it is harmful. Just piqued my curiosity; I wasn't sure if such a bot was possible or not.
