One of two things:
- People who do not know what they are talking about making up “possible” solutions to sound smart. This is a good topic to make up an answer for in this way because it is very hard to prove you wrong, kind of like proving an “it was all a dream” interpretation of a movie wrong. Here is an example where I actually bother.
- The people who write exploits deliberately giving fake answers to dilute any true information that may appear in these threads. I don’t have proof of this, but I assume they do it because it would be extremely funny. I also suspect they start these threads to try and lure out real detection methods from developers who are too boastful to keep them secret.
