There hasn't been a confirmed case of anyone getting banned using Innerspace or any other MB software in a legitimate way. (At least that I know of or have read on here).

There is another software vendor that tries to scare everyone into buying his software.

That forum that you quoted from is out to sell his software and lies about all the other software to make his look like the only one you can use, I've posted on his forum before and had my account banned and IP banned.
