Your submissions are not being accepted because our system has detected you as a spammer. You have 234 additions but only 13 Stumbles since Sept. of last year.
You may have heard that StumbleUpon is a great way to gain traffic for your site or blog, but that is not the extent of what StumbleUpon is about.
StumbleUpon provides a service that allows our users (Stumblers) to surf to different sites on the Web by clicking the "Stumble!" button on our special StumbleBar. We call this process "Stumbling." Please note there is a difference between "stumbling" and adding content. The ideal Stumbler uses StumbleUpon to "stumble" from site to site, Liking and Disliking pages to fine-tune the recommendations we send them, as well as occasionally adding quality web pages to our index for other Stumblers to stumble on to.
Members of StumbleUpon should NOT use the site solely to add web pages or their own content, as this is not the primary purpose of our service. Web site owners or bloggers should NOT expect traffic from StumbleUpon just because their site is part of our index.
