It's not a matter of how any other person or place does it - it's your work, and you get to decide what to allow. ;)

Just a few suggested changes based on what you said the terms were, that may make it even clearer -

"These shaders are provided free of charge for use in ANY PERSONAL RENDER.  They are NOT to be used in or given away in ANY COMMERCIAL product in any way, be it for yourself (own product) or a 3rd party (product and or promotion), including as part of a Commercial Render.  They are not allowed to be used in part, full, or any fraction thereof, in a MERCHANT resource, on the front of a magazine and/or freebie disc, DVD, or any electronic means known or unknown.  They MAY be used as part of a render for a contest or competition where prizes are given."

Thanks for the clarification :)

Cheers,
