Flag as spammer for guests

[AndyF]

Although it might seem a strange idea, I would like to see the option to flag a guest's post as spam.

I realise this will only be able to hide / delete that post as a guests posts cannot be accurately determined just by an IP, but this will then allow us to send the IP to the spam service.

Eventually if enough reports for one IP arrive, that may end up being flagged to further prevent 'member' spammers from registering with it. I realise we cannot really use this to check for a banned IP at post time with the spam service (although in theory that sounds like a good idea it may slow a board down a bit)

Just a quick thought anyway.
