shadowOfShadow's wording is a little unclear, but I suspect he was talking about the email exchange with a non customer complaining about lack of support.
He changed the tar command he typed to make it look like he was trying to install my trial.
The output of tar told a different story though. The cracked trial was distributed as a .tgz with a space in it. Because this guy didn't know to put quotes around the filename, tar gave him an error he didn't know how to interpret.
He left the output untouched, and I was able to determine the name of the file he was trying to extract, google it, and strongly conclude he was asking for support for a cracked version of my software.
