Facebook Group Posting Method

Hello Everyone, I am posting in FB groups almost 3 year.

so 3 days ago made wp site, added some fake posts , posting in some groups ( got near 3k share on whole posts) made 200 $ from popunders and now posts started ghosting, then made new site and with other computers(other ips) , friend's facebooks and etc started posting again but still ghosting.

and i am thinking maybe because its for hosting? because both sites share same hosting(Hostgator), and fb blacklisted my hosting, is it possible ?

Maybe they targeted the group. Try putting a link to some famous sites and see the result. If you get good shares then may be hosting is an issue. Also don't post too many links in the group. It's good to post only 3 links in a day.
