I may be mistaken, but I don't think deer "freshen" up rubs as they do scrapes. So, I doubt there is such a thing as a "communal" rub, however, I am most confident different deer will rub trees in the same area.
sure they do. There are glands located on a buck's forehead, and by him rubbing on the tree, scent is deposited. Theory is that dominat bucks will rub on trees previously rubbed by lesser bucks in order to deposit their scent.
