Correct. but that is very very very very bad. That means that every request that hits the servers for said site will have to go through the if statement for every request. It would probably be better to write up a script to add deny and an end tag of ; instead.
This is actually not a great setup if you get tons of comments, as the comments won't come into effect for possibly 1 hour. quick cache + a 1 min cache on valid outputs might be better.
There is a ton of downtime, and I know it is because of a DDOS, but still it is flaky at best. 10 Minutes all good, then really really slow, and then nothing at all. (repeat)
I think I just am going to go work on my own stuff. (Sigh)
