First, a little background so the following screenshot makes sense. My son is part of an online community that buys and sells art to other members. In this community, there’s a certain etiquette expected when you buy art from another member. If you have a webpage, you are expected to link to the seller’s webpage who sold you the art. It’s considered common courtesy and no one asks any questions. It’s just done.
The individual who wrote this rant had bought art from another member and is ranting about why he/she is refusing to link to the artist’s site. The artist’s signature is also edited out, so the artist never gets any credit. This individual is clearly an entitled, rude jerk. I don’t know if this person is a narcissist , since an isolated instance of rude, entitled behavior isn’t enough of a marker if other symptoms aren’t also present (they may just be an everyday asshole), but it certainly seems likely. The last paragraph seems to be a projection of the jerk’s own sense of entitlement onto the artists whose work he or she has defaced.
