Everything has to be based on something but this is blatant copying and I agree with jaydee116 that this isnt right.
Basing a design on your own research is best, based on others reseach but with improved theory (as in test blocks by someone else) as resonable if the final design is changed enough.
Basing it solely on someone elses design with no care of improving the theory behind it, as i just to make money, is whats is happening and is what should be stopped.
For one off blocks for example my home made gpu silver ww like block, I dont think it would matter as no profit is being made. Other opinions?
I just read a thread over at bit-tech,
linky. He intends to make 10/month.
Note what he has named the block, and the performance claims, and how he justifys that it is better, in true marketing BS style.... Cathar from your post I assume you havent licenced the design to him or even knew his existed before that thread. I think he deserves to be sued.
