Even sites with a very traditional .com domain have loads of phishing duplicates. And changing URL now makes it only worse.
It would be good if someone could create a tool or service that could scan one website and find all the clones with different domains, maybe even creating alert notification when new clone appears.
I am giving small homework to out crypto developers in forum to create something like this

We can use this for eXch, bitcointalk forum, and for any other service or exchange.
