They recently fixed an exploit and reported on it.. so they do fix em its just a matter of time. They post info when they fix bugs, on the lodestone "news" section, "maintenance" and also "Hotfixes" here in this forum.
People who use these things are risking getting their account banned if it is deemed an exploit later on and just because it has yet to be fixed or reported, does not mean for certain that it is not an exploit.

Be careful folks when ppl try to pressure you into using something if you are uncertain whether or not it is an unintended feature in the game.
