Account got limited — fixed it by cutting one traffic source

Account got limited — fixed it by cutting one traffic source
Got the dreaded 'limited ad serving' email. Dug into the referrer report and found 22% of traffic came from one shady Telegram redirect a partner was running without telling me.
— Blocked that referrer at the server level
— Filed the appeal noting the cleanup
— Limit lifted in 9 days, RPM recovered $0 → $4.60
Don't just appeal and pray. Find the dirty source and kill it before you appeal. Steal it.
