two things:

1. There is no 'issue'
2. This is not something I am doing

That said, typically I don't have this much time to engage in discussion. But today you found me during a free time, so I will explain.

You shouldn't self-upvote. It is frowned upon in the community. Why? My upvote is worth $15, if I self upvote 10 posts/day. I will make $150/day everyday. Would you like that?

Accounts like blocktrades single vote is $130. If he self-votes would you like that? If top 50 accounts self-votes, then we can take out the entire reward-pool and no reward will be left for you. Would you like that?
