If we did a 410 to be rid of it now and the page or category came back again what would google make of that.
Google respiders every URL they have ever seen, forever. They revisit URLs previously returning "410" less often than those returning "404". In a conversation with Pierre Far, he said that "Google revisits them (both 404 and 410) because a large number do eventually come back to life."
