I just read this thread on the ultimatemetal forum and it raises some questions about what is ok or not ok when selling profiles.

It appears he use profiles made from other kemper users and tweaks them with added IR's in DAW, then sells them.
As some pointed out in the thread it is not very honest to customers and it's likely not ok to sell profiles made/shared by others like this.
RustyNotes has posted previously on that forum and here on the forum in the commercial profiles section about a previous profile pack for sale. Maybe it's done the same way since he doesn't seem to own the amps?
Rusty Notes Kemper pack
the Rig Exchange clearly states:
"By uploading a public rig, you grant Kemper Amps the right to offer this profile to all members of the Kemper Profiler community. You also grant others the right to use your uploaded profiles without restrictions. Others can pass your profiles on but cannot sell them in any way."
