Elmy, I don't know man, I'd feel much better if EFS would either carry an unmodifiable blacklist of forums it just flat out refuses to post to, or a way for a forum to indicate it does not wish to be auto-posted to (by way of a header, meta tag, or other information), that the user of EFS can not bypass. That's the point where I'd be saying you're on the right track. As Greenie said right now, I don't really have faith in it being an effective tool for "good" webmasters, no doubt that it will be a great tool for spammers.
Similar issue really with Chameleon, I had one of my sites in there for a while and didn't ask for it, and I had to deal with submits of serious shitty quality being hammered through - caused me to just close the site in the end because the hassle wasn't worth my time
