For the most part I agree with the word filters, but when it comes to filtering out hotmail and yahoo emails, I think you should reconsider this.
I understand why it was put into place, but I really think that it causes more problems than it solves. All it does is force people to say "soandsoemail removed", then make a double post with a correction of "
[email protected]" or "soandso (at) h0tm4il (dot) com"...which causes mistakes when adding someone to msn, eventually ending up with a member angrily flaming another member for not accepting their add...
I don't think it really solves anything other than making things confusing and forcing people to find new and more confusing ways to bypass it.
Just my two cents.
