Let downloads and favourites in the gallery count towards the original creator
A lot of people reupload other people's creations in the gallery against their will. I have experienced it too and there's a lot of reuploads of my creations in the gallery, which I have reported, but nothing has been done about it yet.
This behaviour would likely stop or go down to a minimum if you change how the gallery works. I suggest that if someone download or favourite an item in the gallery, the count should always go towards the original creator's original build. So every time a person likes or downloads a reuploaded original, it should only benefit the original creator and never the violator. Much fewer would be interesting in reuploading other's creations and hopefully instead focus on creating themselves.
I guess you could also make a tick box where creators must tick if we allow reuploads or not when we upload a new build. If we untick that box, it shouldn't be possible to reupload it. Creators and the game developers might have different ideas regarding this, but please, let it be an option for each creator to choose. The fact is that a lot of us creators are spending time on creating. Of course we enjoy it but it is unfair that other's can benefit from reuploading which might have taken hours or days to create. Creators generate more gameplay as people download and play with our creations, which is good for the whole gaming industry, so I think you should listen to our wishes too.
