We have that issue too and also when DD visits with STBXH at relatives, some of them have porn there. It's also on phones nowadays as well.
We had a thing happen that was the biggest red flag in false R where its not porn but DD was using his computer to play her kid games and up popped one of the dating websites!
He had claimed he was no longer on them, yet there it was!
I did a faker to see what they are -I didn't even put my picture-but when I deleted it, it never comes up again so I believe he was lying?
So anyway, I am with you on the idea but suspect Tesla's post is right to think about.
