How technically plausible this is** depends on the granularity you want. If you want monthly and don’t want OSM buildings, then Facebook has already got you covered (at least for now). Anyone with half an ear to the forums and the global block list could probably pick a time weekly, or even daily, and say “OSM data is mostly clear at this time”. What is much harder to do is to provide a feed without any vandalism in it.
** and I’m writing this without saying whether this is a good idea or not.
