Clean Slate Glitch?

I keep hearing this is an old glitch.
But I have NEVER seen +extra slot gear hanging around.
So either people are hiding it (for a good reason- looks like hax)
or people didn't know they could do this.

This glitch is old by the fact that it was already out when white scrolls and clean slate scrolls were available.
Though this glitch wasn't known by the average mapler until some time ago, think about this yourself:
It seems like you're the only one knowing about this glitch. Therefore, you're able to abuse it as much as you want to without being caught. Why the heck would you then show this thing to others, which would result in a harder time earning money by using this glitch?
or
It seems like a glitch, I should report it to Nexon asap. *waits 3 months and receives a "We'll look into this issue"-reply*
