Feature suggestion - report abuse button

Hey guys, know you are busy working away

Just thought it would be great to have an option to display a 'report abuse' link/button next to the 'post reply' button as some other systems do.

example the Guardian.co.uk site:

http://www.guardian.co.uk/environment/georgemonbiot/2009/jul/08/climate-denial-astroturfers-pseudonyms?commentpage=1

Possibly limit it to registered users, could be used against you if left open to all guests.

Be a nice extra if you can fit it in, everyone hates spammers.

Thanks
Matt
