when you report a post as spam, a site admin(such as d3rr) will need to be online to deal with these spam reports.

there is another alternative...

allow any user to submit a comment in that thread that consists of a the following single word: "spam"..

then, the admin would already have a chrome extension running on his server that would look for posts that contain perhaps five "spam" comments and then his chrome extension would automatically delete that post.

as a security feature, to prevent people from scamming this feature and incorrectly flagging legit posts as spam, perhaps his chrome extension would only pay attention to "spam" comments from users that have been approved to submit such request comments.

i have already been warned to chill the fk out.
