What you're doing here is not okay, Hysteria. I don't think you're being malicious, but please cut that shit out and don't police people. If they want to provide quality art for free, awesome. If they want to charge a commission to provide quality art, awesome. It's perfectly acceptable given our license.
And as a more general issue, art — visual and written — is worth money. The fact that we provide a lot of art for free does not mean it suddenly has no worth, or that it should only be provided for free.
Using Sunny's example as a tool to enforce your opinions is also disrespectful.
Oh, yeah, and: We would still think Sunny + Sunny's art is super cool even if she only did work for pay.
Please don't do this again.
As a side note, drochfaol: you must never charge for any artwork containing a depiction of SCP-173. Other than that, you're cool. (And I like your art!)
