Remove "add a link" considering adding a link just deletes the content

I added a Surrender @20 link about ahri's new splash art, and they deleted my post saying this:

"We have removed your content due to a violation of the following board rule: Adhere to Board Guidelines

This is false and stupid. It wasn't violating any rules because it was all about ahri to begin with. I didn't break any "rules". If there's not allowed to be a link, then why even have it on boards? That makes NO sense at all. I think the rioters on the boards needs to reinforce their own rules because it seems to me they don't know how to follow it correctly.
