So, I'm not entirely sure about this rule, and I would appreciate some clarification.
On this picture:

I made a comment that originally linked to a project of mine:
http://pervertspokedex.tumblr.com/
Specifically this page:
http://pervertspokedex.tumblr.com/post/68208282131/655-delphox
Because the picture happened to fit in very well with my article on Delphox (and thus, my headcanon regarding Delphox). I removed the link because I wasn't sure whether that would qualify as advertising or not.
Someone subsequently inquired about the reference I made. And I'm not sure if linking the project now would be considered advertising.
I don't want to accidentally break the posting rules, so I figured I'd ask for clarification.
If I posted the link in my original comment, would it have been considered advertising? If I posted the link now in response to his question, would it be considered advertising?
Thank you in advance!
