It costs 0.001 to register and that currently gets refunded. If you used upvote even one time you made your money back and the rest is free! We are managing 20k accounts and we are trying to streamline as much as possible, I'm not sure what would be a better system but a lot of people don't read our rules or try to cheat them to get more than everyone else.
I checked your account and you have cheetahs that show you have copied content, we only upvote original content.
