While this does block the big-name porn sites, there are plenty of other porn sites that this doesn't block. Tbh, I'm surprised that sites such as Rule34 aren't blocked by this app.

Doesnt block most porn sites

Works on some sites but not others, including some of the big ones. Needs to be updated!

Not blocking these sites MYLKED.com, Familylust.com and finishhim.com. It works with most knows sites though. And no, I'm not using it in private mode and I've even allowed it to work in that case.
