If I understand correctly, we are talking about voting with a minus sign for your post. Unfortunately, there are inadequate users who turn bots to vote down. I don't know the motivation for these assholes, but you have nothing to worry about. These are small mosquitoes and their bite is invisible to the cost of the fast pay. As your SP grows, it won't matter at all. Unless such creatures spoil the mood. But they can simply be ignored. These are sick people. And not even people, just bots launched by sick people.
