I have included non-commercial restrictions in my not-very-popular freebies at my own website mainly because: 1. they are only good enough for play renders, but 2. not good enough for commercial render quality. I simply do not want to be referenced and then embarassed. I prefer to err on the side of caution. Agree no redistribution. Also, if the item is a fan-art component, better to assume the worst and spell it out to the downloader that he/she cannot use that for commercial renders. Would everyone in the world be able to recognise what a fan-art item is, if it is based on an Indonesia-published commercial comic, for example ? Finally, any readmes should make clearer distinction among 1. no commercial re-sale; 2. no redistribution; and 3. no commercial renders. I find that often, the creator's intentions for 1 and 3, and 1 and 2, get muddled in the phrase "no commercial use". Just my take on the issue.
