Bot of some kind, not sure what the endgame is.
I just came across this account in AskReddit, and it's odd. It looks like it's somehow amalgamating comments from specific subreddits to create new content, but it's completely nonsensical, and the comments have nothing to do with what he's responding to. It kind of looks like a subreddit simulator posting. Not sure what he's trying to accomplish, maybe just farm for karma for a future spam account?

It's a Markov Chain script. It might just be harmless mucking about, in fact most likely because there are no urls and no-one would be fooled; but you don't have to allow it. Personally I would just ban it and move on. If it isn't your sub, report it.
Are these very common?
I've been seeing a ton of them lately.
Computer Science students, mostly...
How do you know that, is it part of a curriculum somewhere?
It's a common topic with applications in many sciences.
