Your posts are not promotional for those who are resteemed/upvoted/mentioned.
The blogosphere has an exact term for the service you provide: trackback spam. All egotistical claims in the hopes of getting a 0.0002% upvote/follow conversion ratio and some day hopefully become rich. What you do is as old as when the internet was democratised enough for anybody not nerd/geek to login and share their wisdom. Back then they shared their $.02.
You share much less.
