<human>: Summarize the given text in a few sentences.

Currently I am working on a new platform that allows artists to promote and sell their work. Artists are able to register for free, upload an artpiece and sell it in a new/innovative/fun way. 

We allow anybody to register. This has overall advantages and disadvantages. It allows growth of the userbase (sounds a bit marketing/commercial but bare with me). The more users we have the more traffic/audience we can attract. The more visitors the platform attracts, the higher the chances are we can promote and sell your art. Which is our main goal and we would be extremely proud if we can create a fundamental tool for artists to sell/promote their work for free.

This is the issue. If we allow any art/artist to present themselves. This could mean it could become a place with a lot of low quality art. If you take your work serious I presume you would not want to be associated with other art/artists with a (much) lower quality of work. 

What do you think could be a way to distinguish good art? E.g. would a voting system like Reddit work? Should we even have a preliminary voting to determine who can join the platform? Suggestions are very valuable to us and it would mean the world! 

Thanks in advance.
<bot>: How can you determine quality of art in a easy/objective/fair way to determine what art is presented and which ones are not on an online platform?
