Some artists release altered versions or previews of their paid_reward works as a method of advertising them. I'd like to propose that a new meta-tag be created for these previews. The name that I'm suggesting, paid_reward_available, is worded to be consistent with the existing meta-tag making-of_available.
What I'm not sure about is whether to keep this tag separate from cases where the reward is simply a higher-resolution version of the exact same image. Should that be a separate tag that implies this one? Should it be tagged at all? Let me know what you think.
Now that paid_reward works are no longer allowed to be uploaded to the site, the viability of these paid_reward previews has gone up somewhat. I also think it would be a useful tag to allow someone to assess at a glance what sort of works they might get from subscribing to that artist on whichever rewards service is used.
