Spaming my blogengine web site

Dec 7, 2009 at 12:00 PM

Hi, since 1 month, I started receiving spam through my blog. It seems that they are using the "send comment " mecanisme to flood my blog and email box with rubbish marketing ugly comments and products.

How can this be avoided. In admin page, referres, I saw that there are some info for "Possible Spam".

Regards and thanks in advance
