I honestly am with Sahar on this. I can't seem to see the similarities of the text on the two icons? Nonetheless, I seriously am FED UP of having people's work copied. Seriously, it's pathetic. Why do you need to degrade yourself and demean yourself by copying, and replicating another person's work. What is the point in that? There's no creativity, there's no originality within that either. Everyone has their own style, their own talent, and I feel it's completely unnecessary, and completely unwise for someone to actually go and copy shit like that. Seriously, what the eff?
Obviously you did the right thing by confronting the person, I guess the next step is for you to put your copyrights again, as Sahar suggested. I think she's right. It's probably the best thing for you to do at one point. As it is, "copying/replicating/cropping" is NEVER going to stop, so you can't necessarily prevent it all together, but what you can do, is take small steps and work towards it - and by using a copyright, you're sure as hell one step closer :) IDK if it'll help or not - but that's just me thinking aloud. Anyways, Aish I feel so bad for you BECAUSE I know how hard you work on your creations!! That sucks ): I hope whomever is doing this, stops, somehow.
PS. I'll edit my reserve in a bit ;)
