As I wrote in this post I downvote bulk-comments that has nothing to do with my post, or reveal that the commenter has not read or seen my post or is only interested in drawing attention to his/her own posts.
I do, on the other hand, upvote most comments that keeps to the subject - maybe it was better to try this strategy. Asking for upvotes and follows is, in my opinion, contrary to the purpose of this site and the wish for a blogging platform that promotes quality content.
