Does this shit actually work? Seems pretty interesting actually.

I bet this is a scam, probably changes BTC Address g2a gives you and you lose cash and don't get the item you bought.

You're probably right.

I've come across many methods of this nature, and not one was what It claimed to be.

This is a bitcoin clipper. I have came across this myself. Tested it in one of my vms as well. In the "guide" they ask you to download tampermonkey and insert some type of code in there. The code is obviously obfuscated and no one can tell what is going on within the code. What do you know! It replaces your bitcoin address with the individuals bitcoin address instead.

Cheers.
