I wish I could afford a Tesla.  Sadly I'm stuck in a 2003 Honda Element.

I'm not saying pool operators are all running on ramen, but at least in the case of PPS pools, taking the fee and applying calculations on neutral luck is ignoring the significant added risk that the pool operator is assuming, and may be completely different from what is actually happening.  To expect a pool to have DDoS mitigation that can stop the botnet that hit BTC Guild, Deepbit, and Slush in the past, is insane.  There is no way a bitcoin pool can afford that level of service.

I don't know if its the same one hitting ABCPool, or if its a smaller fraction, but if its the same one, no host on the planet is going to be able to keep a bitcoin pool online during it.  Bitcoin mining itself is VERY DDOS-like.  You'd end up catching the majority of legit traffic as false positives.  At best you might keep the website portion online to let people know that the pool is down.
