So... after getting DDoS'd for the third time, I decided to do a bit of research. Load Impact is a nifty tool that lets you hit your (or anyone else's, really) site with up to 50 simultaneous clients for free, and you could pay for more.

I don't think the perp used this thing, but I do know that someone hates me

lol wow. That's kinda cool. So could you pay them to "load test" the mpaa? jkjk

I'm not sure how loic works (or how proper load testing should be done), but I basically just made a simple java app stuck in an infinite loop connecting to my server (with no sleeping).

Basically you just load the page a lot of times, quickly via a program and not a web browser or a command line program.

Yup... while true; do wget url -O /dev/null; done

That's basically how LIOC works except that you can specify it not to wait for a response.
