Just want to share my experience that few days ago I got banned by propeller by submitting blog about amazon product. Propeller will check every submission and will ban you if you submit page mentioning to sell something (such as landing page and page full of ads). If you haven't notice yet please read propeller's TOS before submitting your site. Once you get banned all your site that you've submit there will be banned also. I hope my experience will useful for others. Please share your experience about what to and NOT to in propeller or other social bookmarking website.
