From my limited experience this has less to do with the poster's history than with the site being linked. Some of the sites just seem to turn false positives wrt being spam.

I for one have plenty of dead BuzzFeed submissions to my name.

That's entirely based on the site and not me - fortunately.

Some sites are only allowed from special users. I've had submissions go insta-dead on me, only to see the exact same link show up later, from someone else, and appparently approved.
