I'm using uBlacklist plus these two blacklists that block out spam sites that clone pages from Stack Overflow and Github.

Anyone who has tried to buy something obscure locally will probably find this useful. There are hundreds of fake webstores that pretend to be in different countries (using national TLDs and machine translation), then just redirect you to AliExpress. I have a script that can recognise them and add them to this blocklist.
