We had this conversation three times already, I'm not sure what more I can add. It doesn't matter how good your post or how helpful you are as a person: posts that contain any form of vote buying will be downvoted by stake holders because they are a threat to the model. It is pointless to make a post that will both buy votes and do something positive, it will be downvoted all the same because we just can't allow people to buy votes. In that case it's preferable to make two posts: the one with the added value content and/or where you explain your efforts to help building the community, and the one where you do another attempt at buying vote. That way we can flag and neutralize the second post without affecting the first one.
