I'm unsure if or how to deal with these copy&paste answers:

- https://superuser.com/a/634650/50173
- http://stackoverflow.com/a/18353213

and 

- https://superuser.com/a/634614/50173
- https://superuser.com/a/634635/50173

Since they are both low rep users, they have no "Close vote as duplicate" button, right? They also can't write a comment that they found a duplicate since they have less then 50 reputation. 

I also feel that these are promotional answers from the same user with 2 different accounts because the formatting is obviously the same. He only changed the text slightly. For me, its a strange situation and I would appreciate some guidance.
