I personally don't believe in buying votes nor paying for exposure. I suppose it can help you grow faster, but I believe these services also have a detrimental effect on the social aspect of this site. The way the site was initially envisioned was that it was supposed to be considered a 'GIFTING' system whereby readers who appreciated your work 'gifted' you with a vote. By deviating from that philosophy, we deviate from the original intent. As long as people continue to use these services, the site will attract more and more bots and it becomes less and less social.

Let your own conscience be your guide.
