Linked threads can be removed, but only by the site moderators. On the other hand, you've allowed all writers to link threads, which extends to users who haven't actually supplied a proper thread. Going over the threads attributed to tehdownloader
reveals it was this user who made those erroneous links; clicking the user's threads leads to blank pages, and the thread titles match perfectly with the crumby links. Strangely enough, the user is listed as a writer on the cover page
and the writer list
, but not the summary page
Anyway, back to resolving the problem, you need either Torg or jakelyon, as they're the only two active users with moderator powers on the CHYOO site. However, it seems Torg only drops by the forum when he receives an interesting automated email, and jakelyon admits to only checking on the forums every so often. Therefore, you're better off using the contact form on the site to alert them to the problematic links directly. You could also try reporting the links by accessing them from tehdownloader's thread list, but given that they're only links instead of normal threads and I've never encountered such a problem, I can't say for certain this would report the link instead of the original thread.
