Problem with Spam (ip, cookies, etc)

Hello how are you?
First I would like to thank and congratulate you for the excellent work done so far. One of the best plugins I’ve found, and look I’ve tested more than a dozen.

Well, the fact is that the voting is not 100% reliable at the moment, because when performing some tests, I realized that using a vpn and deleting the cookeis of the browser and even using different browsers, you can vote several times.

The point is that security by ip and cookies is somewhat fragile and easy for spammers or malicious people with the least computer knowledge to circumvent the vote in their favor, for example a brand or company generating false votes in the form of a website for gain public interest.

Well, I think implementing a recapcha, login with gmail or social networks before the vote, would increase and much the reliability of the searches.

Thanks for the time and great work. Democracy Poll has everything to be the best poll free puglin. See you soon, I await news
