also you can have as much accounts as you want, as long as you have only one forum account you use and where you vote in.
If you're referring to ingame accounts, that's right, but it doesn't apply to forum accounts. I thought the rule was pretty clear:
Each user is limited to ONE forum account. If any staff member believes that an individual is using multiple personal forum accounts, for any reason whatsoever, all duplicate forum accounts from that IP will be immediately banned, leaving only the account with the highest post count. Using an additional forum account to break any of AnthemRO's rules will result in ALL accounts using that IP to be immediately treated as though they had broken those same rules. Multiple incidents of having duplicate forum accounts may also result in a full ban. This does not apply to multiple users with the same IP with their own accounts, only to individual players using multiple accounts. This does not apply to in-game accounts in any way, you may have as many game accounts and characters as you choose.
Why would you need several forum accounts anyway, except for bypassing the cooldown?
If you accidentally put in a wrong email address, it's alright, since you are unable to activate the account anyway. Or if you return after several months of inactivity, and forgot your old account information, you can temporarily create a new account to submit a support ticket.
However, it's always safer not to ask friends or anyone else to vote for you and transfer the ad credits to you, since the chance is much higher that you're banned for "accidental" vote fraud (considering that they do not vote because they like the game, but only for the ad credits) <_<
