If you look at https://therarbg.com/ you will see that they have a button at the top you can set to not see Adult content at all. It saves the button state as part of the cookie.

On ext.to you can only disable adult content in an advanced search.

Please add the option or at the very least give us a url to use to exclude it e.g. ext.to/?with_adult=0 or something like that.

Thank you for your consideration.
