Make posts/comments that others respond positively to.

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".
