People across most sites are already much too competitive when it comes to catastrophes, showing behaviour that we do not want to encourage by giving them even more opportunities to behave badly. So we have to decline this request. 

As Kayte already pointed out, we don't have that option so that people do homework, grade homework and do the peeves and Fred & George riddles. We do not want WoP or WoX to become pay to win sites, so that everyone can enjoy all aspects of the site similarily. That's why we sadly have to decline your request.
