A word of warning. If you do something like this even "innocently" or to "try something our"... HTC will likely terminate you for life. It has happened before.
However, this assumes you are actually changing the files HTC sends us. If you are not modifying the game itself in any way, but are still able to do something weird, then it is a bug, not a hack.
Did you have to modify FE files to make this happen?
In either case, I reccomend you notify HTC in private of what you have found. I wouldn't try any of this online if I were you, and I certainly wouldn't mess with any HTC files and then go online. If you do, there is a good chance they will detect and ban you, even if it's not instantly.

A pig is a pal, who'll boost your morale, Though mountains may topple and tilt.
When they've blackballed, bamboozled, and burned you, When they've turned on you, Tory and Whig,
Though you may be thrown over by Tabby and Rover, You'll never go wrong with a pig, a pig,
You'll never go wrong with a pig!" -- Thomas Pynchon, "Gravity's Rainbow"
