Just an FYI -- I don't know if this has been the case for a while and I'm just noticing it, or a new moderation change but a lot of noob submissions and low karma user submissions (sub 100 points?) seem to be getting auto-killed despite some being non-political legit tech submissions.

There seems to be a "guilty until proven innocent" auto-moderation in place and I'm guessing other users are expected to vouch for those submissions one-by-one?

To check, toggle your "showdead" attribute. (I have no idea if that allows you to see your own dead submissions but you can at least confirm my observation)
