Thanks for pointing that out. In addition to, um, goldenrod and grey, what other colors do the ignore buttons come in?
The darker the shade of orange it is, the more ignores that person has.
subSTRATA's is the darkest it gets.
On to the main idea... Is this a business opportunity to run an escrow service?
Plenty of people offer escrow services on the forums, people don't usually use them for BTC to PayPal transactions though.
