Bountyportals.com is one of first, very professional and automatic bounty management platform. Which counts things automatically no needs to give reports. It removes all these hassles. Bounty participants just need to join the portal, connect there facebook and twitter and start liking, sharing, commenting and retweeting. This portal automatically counts there likes, shares, comments, and retweets.
There are many who claim to have these portals, but they are not Automatic. At the backends, they are all manual. Which still kills the purpose of these portals. Only automatic portals can save the time, get the exact amounts in this way no participants will loose there earned money.
