Any Advice when reddit shadow banned

Hi all

I use reddit a lot to share my finding on the best staking crypto interest rates and have been shadow banned.

Here's what happened

• Had my own account "martinratinaud"
• Used the API to create many posts on coins subreddits with information about the best rate I found with my tool https://stakingcrypto.io
• Got shadow banned
• Made an appeal which never had any answer
• At this point, I thus do not know why I got banned but suspected a violation of the API rules (even though I didn't think I did)
• Created another account "stakingcryptoio"
• Began to do the same, but using the API a lot more wisely (1 post max per hour, not sharing a link in the post, answering all comments)
• Got suspended 3 days because I got banned again from r/bitcoin (I know it's stupid but at that time I didn't realized I got banned from r/bitcoin on my previous account)
• After those 3 days, my account is now shadow banned
• Subscribed to reddit premium
• sent an email and made an appeal

So here is my story, I would love any advice because Getting shadow banned because of one ban of a subreddit seems very harsh to me and I lose again all my karma.

Hope some of you will have insights!

Thanks
