Suffice it to say, whatever these cracked executables pretend to offer you as far as advantages over other users in Second Life, or in CCS, are irrelevant because both Linden Labs and the CCS Development team have developed system security metrics which will catch almost 99% of what you're trying to get away with anyways, so risking your Second Life account, your personal computer security and the security of your personal information simply isn't worth it.
So...in short, we advise that you only use officially verified viewers and third party viewers to ensure the security of your account. Be smart. Stay safe...cause you'll get caught anyways. Linden Labs won't be fooled...and neither will we.
This will probably be Internet 101 for most of you but let me state this again just in case you missed the class.
