It's rather hard and inefficient to do that over Tor. It's actually way easier to just use your regular botnet or pretty much every other approach.[1] And then it's rather simple to prevent this with your ordinary approach. There are currently around 1000 exit nodes[2]. Compared to most DDOS attacks that is really small number of nodes. For various reasons (measures that are mostly there to make sure Tor can be used for regular browsing in a usable manner, even when there is people that want to download lots of large files) you will run into limitations rather quickly.
