I am very appreciative for all the offers to donate to maintain the site. Truth is that hosting the site isn't particularly expensive and at this time funding isn't an issue that we have to be worried about. The issue with DDOS protection isn't the cost, it's anticipating how many resources the attacker has access to and getting the right protection against that.
But at any rate, I really do appreciate the fact that many people have extended offers to donate and help out.
