My site is a bloggers driven community site, and to enhance my users experience I would like to offer users to follow blogs of other bloggers.
I am looking for a way to have users submit their blog but it should be checked if the user who submit a blog, also is the true owner of that blog.
With Technorati or Bloglovin you can register yourself as a user, and claim your blog. In order to claim your blog you have to use a certain set of tokens in a new blog posting, Technorati or Bloglovin will check if the tokens are in the blog postings. If they are, you have claimed the blog as the real owner.
How it should work, in big lines as I think is good is as follows;
When a user want to submit their blog, they are presented with two text fields.
1) the url of their blog
2) the url of the rss feed of their blog
To make sure that the url to their RSS-feed is correct, the module should fetch the last 3-5 of postings so that the user visually can see that the provided url to their RSS-feed is correct and they have to confirm this.
After confirmation they are presented with a unique set of tokens which they should copy/paste in a new blog posting.
The module then has to check, during cron, if the security token is in the new blog posting. If it is the blog is therefor claimed by the user.
