Please don't take this the wrong way, but this thread of yours is pointing users in the wrong direction. Here is why. I never saw the original thread where the user was offering credit card info. But your thread made me curious, I researched and found the cached unedited version. If I can do it, others can as well.
The 2nd example is similar. Those with bad intentions now know where to look.
I think it's something to consider because you are unintentionally giving these people some importance.
The person that has cached the threads is the issue which is a secondary point to bring up should a thread like the 2 mentioned be cached and available for any one to see.
Both threads are certainly wrong. So is saving a wrong thread in a cache wrong?
I would say yes it is. But I am just a guy typing on my keyboard in New Jersey .
