By using the anon account you choose not to connect your own account to this comment. So the usual reason to upvote presumably doesn’t apply. But if the common account gets a lot of karma somebody will use it for mass downvoting.
I don’t know if that’s the norm, but the code behind this site doesn’t give karma to a comment, but to an account also. Whenever you upvote something, you’re giving two points: one to the comment and one to the author. Since I’m not able to separate the two, I prefer to abstain in the case of a throwaway account, while I’m usually very liberal in the upvote I give.

The usual reason for upvoting is to promote the comment and not provide the commenter with resources in the form of karma.

Both are usual. (Which doesn’t necessarily means both are equally useful.)
