To answer your first accusation, indeed Yuliya is also a model in life and takes several pictures that are then resold on sites provided for this purpose. We will make sure that Yuliya communicates on video to show you that Kynno is not a scam at all.
The best solution asks her to provide a short video like 2/3 sec that she is working on your project. Since you already have been using images, so providing a short video won't be a privacy issue at all. If you failed to do so, likely your account would get flagged. I am not tagging right now for your explanation. If nothing, then definitely your account will be flagged with a red tag.
And what is the explanation for plagiarism? Often projects show the same excuse as always. You should use the source link if you collect content from elsewhere. This is a red flag for a project.
