I'd ask folk to PM you unless the recomemndations are very general. Not a good idea I think to have wildcamping toptips on the open web. Or you may turn up to a load of old bottles and various human waste matter.
A look at a good map/OSM will find some likely spots and you can suss more on the day, leaving yourself time to discretely scout. I often find that, counter-intuitively perhaps, some of the best spots are quite close to fast roads.
