I'm not voting for your witness because I don't know you. I don't know your personal values and whether they comply with my Hive vision. I don't know if you are technically capable of managing the node, especially in case of emergencies etc. It's nothing personal, and the decision is not carved in stone. I'm evaluating my votes from time to time so maybe it the future I will vote for you.
You should try to get more votes from the community, not other witnesses. It takes time and effort. Also, I don't think mass mention is a good approach - you will receive many downvotes for this.
Good luck with your witness campaign!
