Any public facing contest will receive contributions from professionals and amateurs alike. The dynamics of Commons community will ensure that only pictures within the scope of Wikimedia projects will be retained.

For example, the picture you pointed out has already been identified and nominated for deletion.

We are also identifying possible copyright violations. For example, please see

Maintenance and cleanup work like these is also a part of our work and will continue even after the contest is over.
