Unfortunately, these aren't really the sort of thing that can be requested. The titles most people have are based off their trophy points, for example, getting the Officer trophy changes your title to Pirate Lord. Additionally, our site's staff (admins, mods, and greeters) have their own titles respective to their job. TLOPO Staff and Potco Wiki staff also have their own titles.
Besides that, I only know of two people with unique titles that were given to them, one being a former administrator @Will Nightwolf (Legendary Pirate) . Sorry
