you cannot download a hack here and give it out to other people, that would violate the copyright (at least here in germany, i think it's the same in US).

But you can say the hack has this and this and this features, try to implement them in ibf.

"If so how can I stop others to do that? Is there any solution for this?"
That's always the problem, normally copyright violations goes to court, but the question is: is it worth?
There are noe easy methods to stop such persons
