A free upvote to reverse downvotes.
There is a free upvote service from @droida at http://droida.ch/hive/, but I highly doubt that it could reverse the downvote of a whale, let alone a group of whales. At least currently. This project should get much more support from the community. There should be strong co-operation to reverse downvotes.
Thank you for the mention.
Thank you for supporting the community. I wish you all the best with the project and with everything else. Have a nice day. Greetings from Hungary.
