User stealing and reu-ploading multiple pieces of content without permission?

This user has taken multiple of my original addons and re-uploaded them rather shamelessly:

Original: http://steamcommunity.com/sharedfiles/filedetails/?id=912304203
Re-upload: http://steamcommunity.com/sharedfiles/filedetails/?id=1118747355

Original: http://steamcommunity.com/sharedfiles/filedetails/?id=926228648
Re-upload: http://steamcommunity.com/sharedfiles/filedetails/?id=944049196

Is this the proper place to post about getting them taken down? I’d rather not have multiple versions of the same content floating around without my permission.

Thanks.
