The reason, attacker will go for XSSED.com instead of providing their own database is that XSSED has bigger audience and the chances for someone contributing a new vector are higher. Web2.0 is all about segmenting services in small independent but very useful blocks. So, why bother create a new database when you can use whatever is already available online. IMHO, malware code that makes use of various databases online can impact the Web to an extend beyond our imagination.

For sure you can shut down the service at any given time but that won't make any difference at all. I use XSSED.com as an example, because it is the biggest database available today. If you shut down the service, it wont take long for attackers to find another database and reconfigure the infrastructure to support it as well. In fact, attackers can submit XSS vectors to Google Base.
