Me, too. Although in my case, my consumption of legitimate books usually goes up because I'd get so irritated by the typos in the Z-lib copy that, if the book was interesting, I'd eventually go buy it from a legitimate source just so I could have a properly formatted copy.

It's weird how many I've grabbed look like they were native EPUBs at first glance, but the repeated typos that no human would make betrays that they were sourced from OCRs.
