Looking at your comment history, it appears you've been shadowbanned for low quality comments, and all your submissions get flagged for being linkedin junk.

My suggestion is to create a new account, and post nothing like what you're posting now on it. Don't talk about marketing, SEO or linkedin at all.

Also note that if you use a very anglo username but have less than great English skills, you will attract downvotes for sounding "fake".

Make posts/comments that others respond positively to.
