Yes. this forum is even visible to search engines, so don't give link bots food for their purpose, please outright delete their posts.
Who's still doing this?
I think I know who did it, but it doesn't really matter. It was a slip of a report of ToS #10 violation, and whoever cleaned it up didn't notice the links. In the most recent case, the spammer reposted an Apple mailing list post from 2010 as their thread opener, waited until they had about a dozen replies, then hit it with the link spam in foreign language.
