Final vote: NO
Should probably use something that only allows 1 vote per IP address. I think strawpoll.com and livepoll.io can do that.
VPN voting is also not allowed with this poll. I personally use a VPN and will have to turn mine off to vote on this.
Do we really care this much at this point? Like really… if people are going out of their way to do this, they should: get a life.
Besides that, people tend to share ipv4s in some configurations. Also some people don’t have ipv6.
If you use another service, you have no way to know if a person has an account here or not.
