This is just a case study I did that might help other FB users.
I tested 2 different ways to share from page to groups, and came up with interesting results.
TL;DR: Don't use the MP "simplified method" when sharing from FB pages, unless you really have to.
I have a couple of niches, each one of them has a FB page.
I take the posts from the FB page and share them on many FB groups.
There are 2 different ways to do this on MP:
Use "share post"
(campaign --> what to publish --> share post)
This is the regular way to do it.
Use "share post" + "simplified method"
(campaign --> what to publish --> share post,
campaign --> overview --> advanced settings --> facebook --> choose "use simplified method for facebook share posts (posting the page post link instead of shares) option).
Both options do the same thing: they take posts from the FB page and post them.
So why would you want to use the second option?
I use it in one situation, when I want to disable comments on the groups posts
Disabling comments is a very useful feature when you post to hundreds of FB groups,
and you don't want people to comment with questions as it would be impossible to get notifications to so many comments and manually answer them.
If you disable the comments, they won't be able to comment inside the group,
so they will click on the page link to go to the source of that post and comment there,
hence you will get all your comments on the original post on your FB page, which is great.
But if you try do use the "disable comments" feature using the first (regular) way of sharing from page to groups, it won't work.
You don't get any error message, but when you check the post with the embedded browser you see that the comments are not disabled.
So when I played around with all the MP features and options (@Johnny - this is for you LOL), I found out that if I use the second option ("use simplified method") it does work and it does disable the comments.
So now I had some campaigns that were using the regular share post option (when I didn't want to disable comments), and some campaigns that were using the second option (simplified method) when I needed to disable comments.
And although all these campaigns were basically doing the same thing (posting from page to groups), and were all real-looking accounts, the outcome was surprising:
Accounts that were using the second (simplified) method were getting captchas, and the other accounts weren't.
Maybe a coincidence? I thought so too, until I got a captcha on an 7-year old account, which is the first time ever that this account got flagged.
So I started following the data closely (that's when this became a case study LOL), and all the data pointed to that same result: Using the simplified method was getting captchas.
This does make sense, as the simplified method is posting links, instead of using the FB share function, and we know that FB doesn't like posting links on many groups.
Conclusion: Don't use the MP "simplified method" when sharing from FB pages, unless you really have to.
