Here's the type of response I have used a time or two:
I think it's great that you are excited about engaging in Steemit. And I think it's great to experiment with ways to market yourself and your posts. However, I believe the best way would be to write engaging posts, chiming in on people's blogs, commenting, upvoting and resteeming, earning yourself a reputation and a reason for others to follow you. I get many requests every day from new users to upvote and follow them. I use my voting power on those who have something of great benefit to share. If you are one of those people, I will be glad to exchange with you, but feel there is no real value in just swapping upvotes. Many blessings on your path to a powerful Steemit experience. I hope to find your posts a great contribution.
