1. Do not promote you Propeller link in other social bookmarking sites like Digg or StumbleUpon but especially in StumbleUpon. I attempted to do it in SU. When I first submitted my article, I had no read and prop. After I waited for more than two hours, I checked my stats again. There was no change in stats and there was nothing to do but a small cheat. I submitted my Propeller link to Stumbleupon. Ten minutes later,I had only three props and more than 200 reads and my rating increased to 5.0. After one hour passed, my rating increased to 7.5 with more than 1500 read and only four props. At the end, my article was in the frontpage. However, in the next two hours, my submission in Propeller was removed then I was completely banned from the system. This was a great experience since I am not cheating anymore.
2. Join the groups but send related contents to them. I was joining every group I saw. As far as I remember, I joined more than 50 groups before my ban. When I submitted an article, I was sending it to all groups and doing this continuously. This might be one of the reasons for my ban. You should send related contents to the groups. Try to become an active user in the gropus.
3. Make a lot of friends. Follow their submissions and prop their articles if you like. You can always follow your friends' submission from the “Friends' submissions“ part.
4. Check it frontpage articles and try to understand their main properties. Try to learn what active propellers want to read about and what they prop.

Every article has only 24 hours to come to the frontpage. After 24 hours, even if your submission has been rated to 10.0, it will not come to the front page. It will stay as a passive submission in Propeller. So, you should be as fast as you do. Otherwise, your article will pass away without seeing the front page.

I decided that I would put some strict criteria into my list. 1. It has to be unexpected, not planned, not self inflicted on purpose. 2. It has to be painful. 3. It has to involve someone being hit in the balls. Here is what I came up with.

Warning: Some of these videos have NSFW language.
