The hack only works for clanwar, I already explained this in another thread.
The hack files that was posted on another forum, was 100% similar to the patched hack.
The Blackshot developers did not realize that the hack could be used using that method in clanwar rooms.
Therefore, they did not patch it, that's why the hack only works in clanwar rooms, and have a high chance of disconnecting.
So the answer to your question:
No, they did not make the hack specifically for it to work on clanwar rooms only : It only works in clanwar rooms, because it is already patched awhile ago, just that game developers "missed out" this method of using the hack.
There is no point trying to use thing hack, it is way to troublesome, and can only be used during clanwar.
