Sorry for the confusion. I admit that the guidelines are unclear about solitary mappers working on behalf of an organization. As someone who falls into this category more or less, I'm not obligated to follow them, but I still feel like the guidelines are intended for people like me, so I follow them in good faith. In the interest of transparency, I would recommend you follow them as well, or at the very least, share some details in your account bio about who you're working for and why.

I've started a forum discussion about the ambiguity in the guidelines here:
