Digg stops publishers posting content via RSS

Social Bookmarking service, Digg, has banned publishers and users from submitting their content via RSS.

It is believe alot of spammers were using the RSS feature to post their content onto Digg, and in return was a drain on Digg’s resources to remove unsuitable/irrelevant content.

Since Digg updated their site last year they have seen a decline in users and other bookmarking services such as StumbleUpon and Reddit have increased their traffic.

As you can see from the below Alexa graph, Reddit and StumbleUpon have significant caught up to Digg, whom are only just infront as of Feb 2011.
