[OSM-newbies] Information about deleted items

[doug brown]

I have spent several tens of hours digitizing the location of shrimp ponds near my home in Mexico using JOSM and BING Images.  Recently I opened Open Street Map to find that all of these features have been deleted.  This leads me to pose two questions:
1) How can I find out who delete these features so that I can inquire as to why they took this action?  and,2) How can I retrieve these data which I need for purposes of my own, even if it is determined that they are not appropriate for OSM?
Thank you.
