Every person thinking about one simple persuading reason why not to use Matt's scripts, should read this newsgroup thread. If after reading still insist on using Matt's scripts, they deserve all hacker's fun they'll get - as poor troll Gerald C. Newton got in the thread. If you did not read it, do it. Extremely motivating reading!

We may want to add in PM also some Q and A sections about what not to do, like Frequently Repeated Errors, and avoiding Matt's scripts will be prime candidate - with link above as a proof.
