Its march of 2016 and we still dont have the option to block anonymous people. Instead we got a new like button and notifications. This isn't any different from EA. I've seen similar questions to this multiple times. Someone even said that it can turn into harassment. I dont mind ano users since people have a right to privacy but at the same time we dont always need to report people especially over trivial things which is why we have the block option.

you can block anonymous people from your question, but you can't block an anonymous poster permanently, because that would contradict anonymity altogether. if say one day, you try posting a comment on someone else's opinion, and you can't because it says you or them have been blocked, well now you that they were once an anonymous poster you blocked, thus making the anonymous feature pointless.1
