From time to time undesired content does show up on our Papers. Here are a few guidelines to follow that can help you keep the your Paper.li top!

• Do a "Daily" Check: Treat yourself to a cup of coffee and your favorite content, fresh, daily! Take a few minutes to check your Paper.li and make sure it's up to par with your expectations. We do our best to make publishing easy as 1-2-3, however it takes the human touch to make certain the content, look and feel is just right. 

• Quality vs Quantity: If you are creating a paper from your Twitter timeline and are following more than a handful of people, it is quite possible that your Paper.li can easily become cluttered. If you are following hundreds, or thousands, of people it is possible that the overview is no longer possible and undesired content can easily pop up. 

• Know Your Sources: The best quality content usually comes from sources that you are familiar with, or that you trust. Following reputable sources, people or brands that are familiar to you, or Tweepers recommended by friends will help ensure that your content remains quality. 

• #Tag Check: If you curate papers based heavily on #tags, it is possible that time to time unwanted or undesired content will pop up with a #tag. More than often undesirable popping up in association with a tag, especially if that #tag is trending. If you see repeated undesired content coming in a tag, do a quick check to see if there is a new tag that is being used to reference the topic you are interested in.

You can quickly get a good overview of what is flowing through and see how, or if, you need to modify your content streams. To search on Facebook or Google+ users must be logged in.
