Artificial Intelligence Site and 200+ Content Publishers Daily?

Hello, I am trying to attract traffic by publishing artificial intelligence content.
The site is penalized after 15-20 days.

for the transactions I do to get indexed quickly. I got the news record.
I publish a minimum of 200-maximum 300 content per day. (regular everyday)

Are there people who publish thousands of content to the site with artificial intelligence?

have you been fined?
How was the traffic increase?
In how many days did you increase traffic?

200-300 articles daily per website/blog? Is still too much to look natural...
Maybe do max ~50 daily, schedule posts and spread across weeks/months, and increase with time.
Post articles that target low competition long tail keywords, so you can get some rankings/traffic faster.
Also, if the article quality is low, and has high plagiarism scores, it's another red flag.
