Not so much the model getting worse, but her room getting worse? I have a favorite model that she used to consistently be able to hit a cum show countdown. Then she went into a phase where she thought she could skip cum shows and try to avoid cappers/drive people to her website. Then she went back to doing cum shows and everything was fine.
Then she made an attempt at the top 20 finished in the top 40, but her room has never recovered. Basically in the last few months since her push. Her room has died on like every front even when her regulars are there the tips are just slow or non-existent.
She's had maybe 3 cum shows in 2 months and most nights she has to tap out once she finally gets naked because its taken her like 5 hours to do so and her cam score is dying. I would say some of it falls on the model, but it feels like a lot of her regulars while still showing up, just don't care to see her do anything anymore.
