One rule for one and another one for someone else?

I am entitled to an opinion so here it is. There are some individuals who are not following the rules here: quote

SELF-PROMOTION

Everyone joined this forum to discuss our material, not to hear others showcase theirs. Members who insist on promoting / showcasing themselves, their own websites, philosophies, products, services or other unrelated teachings will be unsubscribed.


Obviously certain individuals are allowed to get away with this guideline above and others aren't. Anybody else notice this or is it just me.
