Facebook Limits [2020] (Share Your Experience)

Hello everybody.
I was curious about Facebook limits on group posting.
I understand it's highly depends on your account as well as the changing text you post on groups, timing between them, random actions.

Can any one share what was the highest number of group post you posted and got away with it ?
If you will share this info, please share account age/activity or other related things that might be important.

Me personally made an automated group poster today with random timing between them + random actions like adding friends, liking random posts/comments, watching stories. And my account is about 5 years, have ~1k friends, and some activity past 2-4 months. I guess it's like top notch.
So I started today with 10 group posts. Will try to increase number each day. If I will get blocked/banned I will inform on this thread what was the number

At the moment I can see that FB marks my posts as 'Spam' since the text is paraphrased I guess it's due same domain. I tried with one shortening services but got marked as spam soon enough. Will try to use different domains maybe that will help. Otherwise I think the limit with the same domain from same account is no more then 10 per day.
