I was actually talking about spammers being clever enough to spoof the size of a file - the link you posted was interesting, but I'm not quite sure how it's relevant to what I was talking about when I said what was in your quote. Could you clarify it a little? If you have any information about filesize spoofing, I'd be very interested to hear your thoughts, since I've never heard of anything like that being done successfully.
And since guests are no longer allowed to post, I'll take that as a hint that my comments are getting on somebody's nerves.
I'll keep this as brief as possible, and on-topic for the feature request forum.
We need a filesize filter, not a spam filter that will take who knows how long to train, and will probably end up filtering out perfectly legitimate results and
some spam, whilst letting the rest of the crap get through. Just like every email spam filter I've ever used.
