blacklist of html tags plugin

[psixtynine]

Can somebody make a plugin that with html allowed, certain tags can't be used?
I'd like to let my users use html, but I want to be able to stop them from using tags that make having html enabled a security risk, such as <script>. This will be for a myspace profile hack i'm doing or for use with the ones already out there, I want non computer literate users, maybe some really hot females who aren't good with computers, to just easily copy and patse stuff from those myspace sites without having to change images and videos into bbcode before using it. A blacklist where you put in <script> and other xss tags there are would be nice. If you don't want to do it for free let me know what you need.

Thanks
