Facebook delete my links

Yes You cannot promote directly your CPI and CPA offers
promote the blog where you have been promoting CPA offers

I promote my blog. Some posts disappear after a few secs if I post it like normally. If I share the same post from my fb page to the same group like before the posts works fine...
I tried this method with another post, but the post disappeared after a few secs even if I shared it.
The two post have the same niche without any sexual content or pictures.

So f@ck u facebook....
