We have had several answers flagged as spam recently:
The answers were trimmed by the author after they were flagged, removing the spammy links and content, but the links are still present in the edits, which is (potentially) an SEO-targeting hack.
On the other hand, while the trimmed answers seem low-quality to me, the remaining text isn't really spam. I'm a little torn on how to handle these.
Is this deliberate spam with the goal of keeping the links in the edit history for SEO, or are these simply low-quality answers? As a policy matter, I don't take moderator actions against wrong or incomplete answers (that's what votes are for), but I do try to keep "broken windows" to a minimum.
I'd like to hear from the community about whether the answers seem like deliberate spam or not. Either way, I think the answers merit some sort of community or moderator intervention, but there seems like some gray area on this one.
