(Porn Blocker Help) You'll see why I posted this in addictions. This is just awful.

this might be the wrong section but idk
So I got found some video shows how to that set up a porn blocker through something in control panel and that really helps. I forget how to turn it off and even when I try to I end up just giving up
But the thing is..google images doesn't filter porn.
I mean if I'm going to PMO, might as well make it more realistic right? I mean how realisitic is having sex with..A PICTURE!?!??!?!?

I've tried google's safesearch, but it doesn't work in incognito and is really simple so turn off.
I'm 14 and there's no way I would not use incognito incase my parents check my history at some point. So what I'm wondering is:

Is there a pornblocker that blocks google images that is hard to turn off? Google chrome's extensions wouldn't work because of how simple they are to turn off.

P.S Please don't ask me how to do the first pornblocker I said that blocks porn websites.I don't want to remember how to turn it off.
