So in this case, I believe that Theymos should change the attribute to rel="ugc" to solve this problem.

This is great suggestion. One weird thing i just found, URL on signature already use rel="ugc". But URL on post doesn't have such attribute (previously i only did quick check and assume all links already use such attribute).

Spammers often won't see things like this and will continue to do the same. I want to say that this kind of improvement will not reduce the spam rate on the forum.
I would suggest a different type of change, that is, Newbies (maybe even Jr. Members) cannot leave a clickable link in their post. Something like restriction in signatures, they can write a link, but it will be just plain text.
Certainly, this type of SEO spam comes from accounts registered only for the purpose of that post. If they cannot do that, it will discourage them, because they certainly have no intention of participating in the forum and building accounts. Higher-ranked members generally do not engage in this method of spamming, so that would be enough from that side.
