You don't like the site so you want to remove your ads from it. Wouldn't it be better to put ads so their readers can go to your site and plead to them there?
On the front page it shows a warning about how applications for editor are closed due to having too many. So it seems the community is still alive and well. Here's their documentation as an epub (in Spanish): https://www.epublibre.org/libro/detalle/2398
There was a very nice spanish community that would scan/ocr books and convert them into epubs. They had very high standards and their forums were full with epub documentation, best practices, boilerplate/skeleton files, scripts, etc. To the point their curated epubs were better than those of some publishers.
It all died when one of the founders was arrested.
Edit: it seems my information was incorrect, the site's owner sold it and the new owners wrapped the download links with malware and closed the forum. Users left and the site closed.
Having a dynamic IP from the 3rd world, I can't help but notice how so many of the sites I visit are behind CloudFlare. 70% of the time I have to solve a captcha the first time I enter a domain during my browser session. This space could really do with more competitors on their same level.
