Ensure no duplicate votes

[cletusc]

Currently you can vote on a pull over and over. Verify IP or userdata and add an option for duplicate voting.

[Muddr]

Maybe adding a useLogin and voters array to the poll schema. If useLogin is false then voters is an array of IPs and if useLogin is true then voters would be an array of usernames for that pollType(Twitch, etc.).

When loading the poll if the voter is in the voters array then redirect them to the poll results page.

Poll Schema

    pollType: String,
    useLogin: Boolean,
    voters: [String],

Example

• Anonymous poll pollType = '' useLogin = false voters = ['12.34.56.78', '23.45.67.89', '34.56.78.90']
• Logged in poll pollType = 'twitch' useLogin = true voters = ['username1', 'derp', 'herp']
