Copycat

I haven't been a part of Etsy for a long time but, I have recently become aware that there is some copycatting going on. I know that Etsy frowns upon this and I was seeing if anybody else had some feedback on this topic. Now, I am aware that most people get great ideas to do something by seeing someone else doing something, or making something etc, etc, but having the SAME pattern or recipe is obviously stealing. The person that got stolen from is bummed to say the least and Etsy has gone after them time and time again, but they continue. Anybody have any thoughts on this?
