You can use these extracted users for your targeted tumblr social marketing. You can send the users fan mails, ask them questions, or follow them and hope them to follow you back.
Note that there can be quite some duplicates in the notes of a post. For example, if it shows 10,000 notes, there can be possibly only 3000 users because many reblog and like at the same time, and some can even reblog multiple times.
You can give me up to 10 posts in case there are not that many users in one post. I will give you 10,000 unique users – no duplicates. Note: a “post” URL MUST contain “/post/”.
