Need help on selecting winners for my Contest

[Valii]

Hello guys,

I wanna launch a website based on image contest. Let's say people come on my website and post images based on a theme i will pick. How i should pick a winner based on public needs.
If i will award the ones with the most likes,shares on my page someone can easly do some bots socials and it's useless.
I need a good strategy to make visitators to vote the best Images without register needed and after that the most voted image will win the prize.

Anyone can give me some ideas ?

Thank you

This was also my problem when I was launching a contest in an offline business. Some were cheating and it was hard to confront them. I'd also like to know the answer to this if anyone knows a trick

You could either pick a random winner using https://www.random.org/

Or you could put a vote system. Like 1 vote per IP.

Random winner it's useless. Cause i wanna select winners based on public appreciation. 1 vote per IP it can works but when spammers will seen the content, cause it's paid contest they will do anything to cheat so i need something more secured

A comment and like system with captcha would do.

How about two winners:
1- the one that got the most likes / shares
2- one "staff pick" (they image you like the most)

You can check manually if the first winner is cheating, just have a look at their posts and when their social signals look fake disqualify them.
People will stop trying to cheat after you disqualify the first few ones.

or I have a better Idea. After hitting the Vote button, put a "are you a human captcha". this will be awesome.

Make it bracket style, where the winners advance to the next level.
