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]:
[link/pasted code]
And that’s it. At first I thought it was a straight-up 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?
This is the user. 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. It just piqued my curiosity; I wasn't sure if such a bot was possible or not.
