MMo dbases

How do sites like ogaming, warcry, stratics have those big (almost complete) MMORPG dbases with monsters, quests, items, etc ?
i`ve searched all over and found nothing about those dbases, although i`ve seen there are many websites that offer information about items, quests, weapons of different mmorpgs.

i want to make a website for that kind of nitche and it`s quite "ugly" to copy/paste info from other websites

thanks

Simple, they just contacted the company who made the game and asked them for info. Or they just made it up themselfs.
