that dll should really be fixed
First, it can't be fixed. It's the nature of the DLL, it exploits based on engine design, so to patch it you'd have to rewrite large parts of the engine.
Second, these topics need to stop being posted. Yeah, it's around. We know. People are dumbasses, people are starfishs, people are going to distribute BLHack.dll. At this point we've had literally dozens of drama topics about it, but there's nothing to do about it. If you want to report someone for use / distribution, PM Badspot. Currently, the only thing this topic is doing is creating a space for people to repost how much they don't like the DLL and teaching people where the most recent dealer for BLHack.dll can be found.
