If you referring to the 'pop up' at the bottom of the page... you don't have to accept. Just close the box via the 'X' at the end.
I've not seen many porn sites or porn hosts that don't have 'pop ups' or malware/virus attempting to download... I proceed with caution in these cases.. and with that being said, here's my process in accessing the videos from the host that MGuru posts....
I am running windows10 with IE11 in 'InPrivate Browsing' mode. 'Tracking Protection' and 'Do not track request' have been set on.
When click the 'play' on the video, I know that a pop up will appear. I anticipate that happening and immediately position my mouse to the upper right corner and close the window as quick as I can. Clicking again on the 'play' will start the video... if you stop/restart the video, the pop up will happen again... anticipate it... also, I have Norton AV. Knock on wood... it's so far has provided excellent protection.
Hope this helps
