Quite a number of links are self-submitted, and it seems to be well accepted. What isn't accepted is self-submission of link-bait / pointless / off-topic articles, especially when your submission history shows that those types of links are all you submit. That frequently gets called out in the comments, and I'd imagine could lead to banning if it continues.
