Sure, just a bot that upvotes people for you. I wanted to upvote the post, but my voting power is lower than usual, so rather than just leave a comment, I can also get you a vote as well. Sometimes it takes a few hours, just depends, the person that does it I believe does it manually, so that's the reason for the wait. The people doing it are part of a charity that is planting trees in deforested areas in Cameroon.
