My blog is SPLOGged, but it is not a splog !

Hi evreybody,

I have a problem with anti-splog.
I have made a mistake declaring my blog as SPLOG.
Trying to cancel this information, I declared the blog not a splog, I desactivated the plugin, then reactivated... but now I have a message on the blog telling 'it is a splog' when I go to the dashboard.

How can I suppress this message ?

Thanks for your help
