An important point regarding reply-to links was identified by David Gammel: the same knuckleheads who link farm on dummy blogs can spam the conversation stream.
As we puts it:
Neat idea, but I'm not sure it would solve the spam problem. Won't you still end up with spam from bogus blogs that create false 'reply-to' links? It would invert referral spam. I guess the bogus sites would be easier to filter but it would still require overhead to manage.
The efforts to combat index spam in general would be helpful here as well. Technorati can rate the value of conversation elements with its authority ranking. Google's page rank for a for a blog could also be a factor. Spammers inevitably acquire new tactics and new innovations will have to be put into play to counter those tactics -- the history of SMTP and NNTP message stream use provide good learning precedents to drive those innovations.( Aug 25 2004, 01:27:36 PM PDT ) Permalink
