Exploiting EPL Predictions

Dear DevilsMMO,
As reported this case before, you can change your matches after they have been played. This was reported by me to ANATOLIAN few weeks ago, then the system worked fine as all the matches were locked before they started been played. After seen 20 people get 10 matches right I had a feeling that the system was broken again and SOME people changed their predictions after the results.
This week, when I went to check who I predicted for once again, I noticed that the matches were "not" locked, therefore you could change your predictions. ANATOLIAN warned people about been banned permanently from this competition if they repeated their action. Just to prove that system was broken, I changed one of my prediction from Manchester United to BlackBurn after the match was played.
I request for this week been canceled, system been changed and those who exploited the system once again and won the PRICE last week that they shouldn't of done last week been banned. ( If they abused the system).
These are my predictions before I changed it:

I have not changed my prediction back to Manchester United, and haven't done this to abuse the system, only changed this so I could show you that the system was abused. I am not changing it back to Manchester before, you guys check that I'm right as you know some people are "clever" enough to say this MIGHT be a photoshop etc.
Cheers,
Ronaldinho
