What are the solutions (plugins, scripts) for creating contests?

Question

Survey tools

Hello.
Tell me how you can implement a contest and vote for work for a site on WordPress? I would like to have protection against cheating, so, as an option, I suppose voting through social network accounts (user registration is not currently available, but, with the development of the resource, it may well be introduced and then the issue of cheating will be a little less relevant).
For example: the contest entry will be in the form of text with images. How best to implement? Users will send works to the mail and the admin will then create a special section and category of posts "competition", in which he will post each work as a separate post? Collect votes for each post with a competitive work separately or make a general voting page? Please share your experience, observations and solutions. All options are considered (plugins, scripts, etc.).

Good afternoon! If the question is still relevant, then I can offer my platform for organizing online contests Competizer.com . We have our own engine, not WordPress, there is protection against cheating when voting, including authorization through social networks. Works may consist of text, images, video and audio files, any other files and links. We have a fairly powerful admin panel where you can work with user applications, there is functionality for expert jury evaluations and popular voting.
