Dear Steem Blockchain Business Partners,
Steemer.app(https://steemer.app) is the most reliable auto-voting service that is now serving more than 100 business steemit accounts.
After receiving numerous requests on comment voting capability, the feature finally has been added to the service and now you can setup voting machine to vote on comments as well as posts with precise voting criteria that includes "tag inclusion", "tag exclusion", "daily max voting count", "weekly max voting count" and more.
Best,
Steemer.app Dev Team
