Dear Sir, I am new here. Is it illegal to do this? I saw people doing this and felt that minnows can help one another to upvote. I have been organising free contest without the need to upvote before. I am surprise to get downvote from you. I am sorry if I did something very wrong but I am really not aware of such a rule. I have never flagged anyone or downvote anyone before as I seek friends rather than enemy.
