In ways it could. People who scam off other sites, social engineer, they got the money. You think people who make $500 everyday would care about $25 or something as low as $100? Although this won't happen most of the time, it's a precautions action. All I was reading was pros when I was scrolling through the thread, I don't think I've seen anything as a con. What would make it more easier if people started posting about cons and pros and you'd add it to a list onto your thread.
Aside from that, I support this 100%
Pros:
More money to support site. (Even the scammers I was talking about support it)
Cons:
More scamming threads(possibility)
