The vote record is stored by cookie and not IP, so feel free to stuff that ballot box for the 'Jah.
I looked into the polling service being used by Thrasher and made my own poll. For the free version of it, all the votes have an IP (Internet Protocol) address attached to them.
As shown below, I didn't upgrade to a paid plan to see how good the IP restriction setting is.
I'd assume Thrasher paid (and has hopefully enabled that restriction) since the free version limits a poll to 2500 votes.
Perhaps that setting will prevent your vote from being added to the total tally if you are using a cookie bypass or "something else" to allow multiple votes from the same IP. Yes, someone could totally wreck this poll if they use the right methods, so it probably shouldn't be too trusted as the people's vote.
Anyways, this is probably one of the toughest SOTY decision years I've ever paid attention to, so props to whoever takes it. T-Funk's part makes me want to skate, Nyjah's abilities are mind blowing, Tyshawn's pop is next level, and Louie's finesse can't be touched.
Hopefully we get to see one of those videos where a bunch of pros, ams, filmers, photographers, and industry people are asked who they think should take it this year.
