Spain has it right in prohibiting this 'pissing to mark territory' muslim move.
"Islam has a long, documented history of marking territory through public, highly visible prayer in symbolic spaces. It’s not incidental — it’s intentional. These events are not mere cultural expressions; they are deliberate shows of presence, rooted in a history of triumphalist expansion."
