One way to make the job easier for the clones would be to include a "spam" link in tha link line below all posts (or only below all GUEST posts). Anyone stumbling upon a spam post could just click on "spam" and the message would be transferred automatically to a spam thread that is accessible only for clones.

They would have all the spam posts on one spot (which makes erasing them easier and could retransfer all the posts to the original thread which mistakenly or out of ill will have been designated as "spam".

No need anymore to advertise spam in the help forum, just click it away.
