If KODI developers were smart enough to just update KODI to 17.2 and disable the unknown addon function not see it anymore, make it so that if anything is changed it disables KODI 17.2 as a whole, change something on KODI 17.2 so what is changed only works if you have 17.2 if you have 17.1 that function will not work, this might solve the issue with these so called KODI box sellers, I myself have never purchased one.
