This looks pretty sketchy. The FAQ, blog and DMCA links from the posted page all 404. Seems odd for a site that supposedly has been providing ebooks since 2009

I'm not even going to try clicking the book, article or sign in links

Been using it for over 5 years, it's legit.

Site is perfectly fine. It’s nearly the same content as libgen but with a nicer search engine and a recommendation system.

I've been a long-time user of z-lib and never had any issues. YMMV.

The site is fine. I've never encountered any problems.
