Today there was a spam post (copy for <10k users) to Science Fiction & Fantasy whose purpose appeared to be to induce people to click a malicious link. At least one user did:
First of all, the answer box is not the place for this sort of thing. Secondly, what images are you alleging are being infringed? I see no images on this page that would belong to you, and the linked document is coming up blank for me. – jwodder 2 hours ago
(Emphasis mine.)
At that point the post already had at least a couple of spam flags, but that's not obvious (other than the downvotes) to someone who is a lower-rep user and outside of review.
The system can already recognise text URLs in post content, and it rewrites them into proper anchor tags; my suggestion is that if the post has more than one spam flag that any links be disabled.
This could be accomplished simply by writing the anchor tag as <a href="#">[link text]</a>
; bonus points would be to create a pop-up with a warning that permits click-through.
