I believe PornoLab has a CAPTCHA only if there has been a failed logon attempt (otherwise there is no problem).
Originally the script used Special Login, but that caused a cookie fight with the browser. The new method is better... when it works.
Actually, I'm having an issue with Bit Che searching it as well. I'll play around a bit and see what I can do.
Edit: I can't fix it. If you login with your browser it sets a new cookie. When you go back with Bit Che it isn't properly requesting a new cookie for itself. I've played around with the failed and failed2 and cannot get a combination that works.
Either we need to go back to Special Login which means you have to manually reset the cookie every time you use Bit Che, or stick with the current script and never log in with your browser.
If you DO login with your browser you need to go to the settings.ini and delete the Poronolab section in order to get things working again.
I'm stumped. Looks like the same issue is going on with rutracker as well.
