I’ve just installed Chad Everett’s MT-approval plugin v0.1.1 to at least try to stem the flow of messages from vendors of chopped meat products. I went out this morning c-spam free and when I came back at 14.15 I had 55 comment alerts in my mailbox all with exactly the same message (crap speelinges & grammar bad with html too much wrong also).
The upshot for you is that if you leave a comment, you will need to preview it first before posting. If you just post, it displays a message, which doesn’t spell this out, but it doesn’t let you post either.
Not tremendously tidy, but hopefully effective for now. Mail me (lloyd at etc…) if it’s giving you the runaround (unless you’re a tinned pork pusher, natch).
