[WEBSITE] Must have SteamID linked to vote in POTM

[Squidward]

I'm pretty sure someone has made a fake account just to vote for themselves in player of the month. It doesn't happen often but it obviously can and does happen. Just an idea but it could be avoided if you're required to have a SteamID linked to your profile to vote in POTM. Not sure how easy it is to implement something like this because I assume you would have used this in various situations already like needing to have a SteamID linked to make an unban request or to post in abuse reports.
