JFBC creating many "pages" indexed by google from the login proccess

All JFBConnect login URLs are generated through Javascript. They normally aren't indexed by Google as they aren't in <a ..> tags on the page. With that said, Google does do deeper scans on sites to generate the Javascript URLs that could be followed and other such behavior. There's nothing we can do to prevent this behavior.

this creates a lot of indexed pages with no content, which are basiclly duplicates of one another... very bad for our SEO.

Yes, duplicate *content* is bad for SEO because your valuable content page gets split into multiple URLs and the link value is distributed as well. The URLs you're mentioning are not content at all, Google may show them as 'indexed', but that doesn't mean that they are showing them in any results and the SEO value of those pages is zero no matter how many times its divided.

If you're concerned though, I'd suggest:
* Downloading the index maps from Google and checking the referring URL that's showing those pages. Then, you can check the page to ensure the URL isn't in an anchor tag somewhere. If so, let us know and we can help investigate that.
* The URL map should also help understand where all those referral links are coming from. I don't think you're saying Medium, Zomato and other sites are pointing to our authentication links though, so I'm not sure how that's related to JFBConnect.
* Use the Google Index -> Remove URLs tool to setup a wildcard removal search or add the JFBConnect path to your robots.txt file in the disallow section, like:
I hope that helps give some explanation and ideas, but if you need further assistance, please let us know.

We haven't seen this issue before, and I'm definitely confused as to what's going on. We even checked our own webmaster tools info after you posted and this site definitely doesn't have all those pages indexed.

So, in the CSV download of your links, those other sites are shown as linking to one of the JFBConnect authentication pages? If so, yeah, I'd have to imagine that's some sort of really weird bug. That CSV download should show the Referrer URL though, which means you can go right to those other sites and check the exact page to see if they are linking to anything on your site. That will help confirm.

If the referring URL has no links to your site, you may want to submit a report to Google. They make mistakes too.

That is definitely strange. I'm very happy to hear that it seems to have resolved itself.. somehow
