People who hang around these kinds of sites generally don't like things being advertised to them - especially if it's in a somewhat forceful manner, or being done on a large scale

Consider how you would feel if someone decided to promote their niche interest website unrelated to CRBA/MLP on your site - along with dozens of other sites - with either just a link, or a big wall of text spouting how wondrous and life-changing the contents of their site is

I suspect your (and your users) reaction would be along the lines of "TL;DR" or "delete this" too
