Look at this text from the MySpace profile editor page (I added boldness):

You may enter HTML/DHTML or CSS in any text field. Javascript is not allowed.
Do not use HTML/CSS to cover MySpace advertisements. 

Who wrote that? A real web-designer would know that DHTML and Javascript are the same thing. It also doesn’t say you can’t use “DHTML” to cover the advertisements (because they think it must be different to javascript ).
