From the Release Announcements board, there is this rule:
Trying to cheat the vote system is strictly prohibited. This includes, but is not limited to: creating fake accounts, asking others to create accounts to vote for you, publicly spamming vote requests. You will be banned from this board and your post will be removed!
I’m not sure if all rules are the same for game pages too, but for future reference it’s better to ask first if you are unsure.
