About ready check perm bans perm bans

So recently I have posted about my account getting perma banned for missing a ready check.
Many of ppl here have said that you can only get perma banned if you miss hundreds of rdy checks.
I have opened like 20 tickets with customer support to learn how many times you need to fail rdy check in order to get perm banned, and after 20 tries i get an answer (well, sort of).
The answer is 12. You need to miss queue 12 times to get an account of 10 years perm banned. And its not 12 in a row btw as i have never missed more than 3 in a row.
