There's no problem in this area.
This is security that you're just not going to find in online gaming trades.
There is no "legal" action you can take against a RuneScape trade in most most most cases, and even if Sythe had "100% scam proof" and reversed it, there would be problems.
Say they'd spent that money and blame Sythe for taking it back. No matter what you're doing, you don't want a bank coming after you, especially without a license to operate in this area.
The reason we can only accept donations is because they can't be taken back. Richard doesn't have the paypal account for transactions, that takes money and a physical site of operations.
Big dreams for small things, one step at a time.
Maybe if we get enough dog fuckers...
