I was trying my hardest to enforce my ATC transmissions but there were a lot of people who decided to just flat out ignore me or not even tune into my frequency. Had I had the power to enforce/ghost, I would have removed those airplanes not following my instructions. That plane that was on the runway was sitting on the runway spamming transmissions to takeoff, and every time I kicked him off my frequency he tuned back and continued to spam, there was nothing I could really do.
I considered using one runway for arrivals/departures but realized I didn’t have the ground frequency and the ground controller wasn’t coordinating with me, which makes it even more impossible to tell planes the runway to takeoff from (which was why there were 5 planes on 09L/R asking to takeoff, making it very annoying).
Thank you for the feedback, near the end of my session it got very crowded.
