I'm not sure what these are, although I've been accused of being one from time to time. To some, apparently being able to spell and having a passing aquaintance with the rules of English equates with snobbery. (which are the grounds I've been accused of snobbery, not for being sardonic jerk, which would be eminently fair)
I'd say the reviewer who probably came closest to the definition of RIA snob was the long departed Pbeavr, who viewed himself as the conscience and guardian of the site. He did a lot of useful stuff, but he could be damn annoying about it too.
There have been a few attempts since at this, but they have all dwindled away, usually because the reviewers who attempted it were unequal to the task they set themselves.
