Never fall for these paysite....
They usually make their business by creating a VERY abstract definition of a bug/cheat.
Example....
Their "get chocobo easy" cheat could consist of being like "If you start at 23:50 with the chocobo quest, then you can refeed the chocobo at 0:01 and skip an hour!"
Most of the stuff they tell you would be stuff you could hear in your own LS or just in tells from friends. Their are usually very few bugs in games that stay hidden for long and when they are not hidden they are squished.
If you really want to cough up any kind of money for gaming advantanges...sites like this one (Allakhazam) are your best bet. Resource tools, not cheating.
