The AVC comments has been experiencing a wave of comment spam that has largely been replies to legit comments. I appreciate the community for flagging it and our moderators for nuking it. Keeping the comments free from spam is important to me but not an easy chore.
One idea I have, which I don’t even know if is possible in Disqus, is the idea of limiting replies to longstanding community members who are registered with Disqus and have high reputation scores.
What this will do is eliminate the reply spam, but will also make it impossible for new commenters to reply. They will still be able to leave a comment.
I think the pros may outweigh the cons.
