Bug Report about Credits

I found a bug about the credits

I was thinking about it before so I post something in a forum, my credits was added by 10, but when I delete that post my credits is still [not reduced by 10], and when I post again my credits added by 10 again!!!

O_O Then we can earn unlimited credits

Please don't do this that's cheating

We won't man... he just discovered it...

I have not found any solution to this even though I have asked to Forumotion.
But will anyone do the cheat? It's a very boring thing to do, lol.
But to avoid flooding to gain points, I have cut some credits when I posted something like [W1] or [W5] when someone floods, the number shows the warning level ^^ . The higher the more credits are cut.

EDIT:
I have solved the problem by disallowing members to delete their own posts.
If you wish to delete your post, PM me with the link and quote so I know which post you want to delete. I will then cut the credits from you.

Anyway deleting the post and reposting is very boring thing to do only for 10 credits...
