Oh my OW instructor went to work for the dive shop that has had two training deaths (both with the same instructor, still in teaching status AFAIK).My open water and advanced open water courses were also full of standards violations. Like you ... how was I supposed to know? I learned it after the fact when I became a DM. My open water instructor was eventually suspended (may have even been expelled) from PADI for violations. My AOW instructor thankfully stopped teaching before she got caught. They were both awful. Thankfully I found some solid mentors/buddies and eventually hooked up with quality instructors for my rescue, divemaster and my technical training.
