The way is to do something with that is wear something visibly your brand but not provably you. So then you can copyright strike them, trade mark attack!, and re upload and monetize.
I wonder what country this is. The penalty for publishing piss videos without the right paperwork is probably much more severe than the penalty for pissing in an empty alley.
In the US if they're pissing in a public place like a sidewalk or street etc anyone can film it and post it all they want. Just don't mark the content "for children" when you post it.
Nerevar, behold the grand utilization of space within my mighty halls. I have constructed a new server room, boasting Yotabytes upon Yotabytes with layers of redundancy to store and host videos capturing individuals relieving themselves in or around Dagoth Ur(the city).
What's this? No, Nerevar, you fool, it is not one of my peculiar fascinations. This serves as a means to chastise those Dunmer who have lost all sense of decency, soiled by their impertinence. Since ascending to godhood, I, Dagoth Ur, have long abandoned such base necessities. It vexes me greatly that there remains a Dunmer outside my domain who still indulges in such actions. Of course, in my mortal days, I too partook in such mundane activities. What a grand and intoxicating question.
But now, Nerevar, do you wish to partake in the viewing of these Dunmers, so devoid of dignity?
