OP is playing the wrong game. They should have filed a trademark for the name and start sending legal letters to the copycat.
This is why open source projects like Firefox hold trademarks near and dear.
Last that I paid attention, filing a trademark was a 4-figure (US$) move, and defending it internationally could easily be 5-figures.
