Facebook Domain ghost ban real... or just something in my head?

My experience and why I think its real, if you have experienced the same and came out of it do suggest something.

At first when I shared my link with my targeted pages my reach was pretty good, my response was pretty good and clicks were about 15% - 20% to the site. Then I got greedy and started spamming my links in my own pages where there weren't many followers but I thought whatever even if I can get a couple of clicks, then I got a fake accounts, joined some groups and posted my links. After 5 minutes my account was baed from joining and posting.

So from the first few shares to when I started spamming, now when I share my links with my targeted fan pages.. I get decent reach but horrible CTR. I get decent shares and Idea but there are no visitors!

I feel like facebook has a trust factor for every site which is why when I share a popular site it gets amazing reach and ctr but when I share mine I don't get nearly as much.

After research I found that these could be the reasons why this happened:

1. Spammed too much too fast
2. Having "2 parts to one post"

Now I am not share if it's real or something in my head but anyone experienced this? Anyone able to fix it?
