Thanks. I had a look at your post and I agree it is rude. To self vote such a relatively large amount and not even upvote the post is just really poor form in book. It happens to us all.

There is starting to be some co-ordinated response to this sort of bad self-voting behaviour. Have a look at @sadkitten it is one I am supporting and it is an approach which is hopefully going to start chipping away at the problem.
