I can’t remember exactly what it was (Emby?) but I distinctly remember one time having my ticket closed because they scoured the log and found mention of a torrented file. They basically had rules that stated if the logs showed evidence of certain things, they’d outright refuse to assist you. Not sure how common that is though.
Sometimes there’s also just file or directory names I’d rather not reveal. So I’ll do a find/replace with some generic titles. But nothing gets deleted outright.
