Before you get going, you'll need to log in with your delicious account. There is no trick here and you don't have to worry with your personal data. Due Delicious public feed constraints, using the API was the only work-around I found in order to get things working properly.
Don't be scared, here we will just test all urls you have in your delicious account to see what is deprecated, redirected etc. Absolutely no url will be deleted or changed in any way during this step.
The process of fetching urls can take a while! Be patient and remember, you can stop the processes whenever you want.
Success 0 items found
Problem 0 items foundDuring the step2 as long as the app finds a bad url it will appears in a list below. Just click and remove. Be careful at this time, some "errors" are just timeout. Use the try it button to see by yourself if the url is good or not.
