Feeling the need to cite a particular work out of convention or for social reasons is understandable and very common AFAIK, but I'd consider it a part of academic rigour to at least take look at the work one is citing. Blindly citing without ever even laying one's eyes on the work doesn't sound quite right.

Of course if nobody can get their hands on a particular work, as seems to be the case here, that makes things kind of hard. But I'd expect most works you need to cite in a fast-moving field such as CS to be available at least somewhere, even if it takes a bit of effort.
