Edit - It isn't that, I actually like your work. I just admit I found it unexpected. Never expected to see artists upvoting stuff related to their own work here, but then, I do focus mostly on the Japanese work so maybe I just missed other occurrences of this kind of thing.
And why not - if I like the comments I am allowed to upvote them if I wish. Why are you so concerned?
I didn't upload my stuff here - someone else did - I have stated before and I will state again I don't want my stuff here because I don't think it is the right fit for E-Hentai.org.
However, since people want to take my stuff from other locations and put them here I think I have the right to upvote those comments I feel are in fact of value to comment about my work if I wish.
If you add a comment - both negative or positive I will upvote you. If you just add a bitchy remark or your own personal hate of the material because it doesn't suit your ideals then I won't upvote, but I don't don't downvote either. It is of no value to me.
