There are many things that I like about WordPress over other companies however, I am sure that you will agree with the one that I like the best!
The great control over people with foul writings, jealously coming to write on our posts because we do not allow their type of advertisings.
If they wish to advertise on WordPress they need to contact WordPress, otherwise they are spam!
However, if they disagree with a posting a good clean debate is often helpful for both side on that disagreement and a compromise will often be agreed on? :-)
