Due to spam concerns, Business Week is considering turning off trackbacks.
We understand this, the Tribble Ad Agency get’s about 45 or so bogus trackbacks per day, and only 3 or so vaild ones. We suggest they don’t… but the trackback system should be upgraded to reflect a spam filter.
Most trackbacks use the nofollow tag, so there isn’t any search engine help from spamming them. They must be going for direct traffic.
