I am sure there are many inactive guilds and cities that have had no one log in for years.
I know there is always a chance of a player or guild deciding to return after a long absence- but I will bet there are many abandoned cities out there.
Is there a chance of the cities being auctioned off? Guild names reset? After a reasonable time, 2 years, 4 years, or whatever.
Probably not, but my mind wanders
