What kind of scams are you guys talking about?
At this point, more than 2 disputes at a time with a vendor would likely throw up red flags for administrators.
Besides, if people are following the rules and using the escrow system, what is the hesitation? Buying from an unknown or sketchy vendor is your own choice. If someone asks you to FE or they won't ship, you should contact an admin, because that has been explicitly prohibited for 30 transactions.
Do research. Contact beforehand. Don't spend more than you can lose.
You can be smarter than the scammers if you decide to be.
