Whether pirated content is allowed or not seems like it'll depend on who the mods care more about pleasing. Artists with a pay wall in an oversaturated market who use manipulative tactics to get a leg up, or consumers and artists who make their work available publically. Attention and resources are limited and artists who don't block their work are probably underappreciated. Either way, anybody who pays artists with previews and a paywall is a sucker. They should be boycotted.
