Working "Social Lead Freak" replacement?

I've been out of loop with FB PPC for a while, but getting back into the game.

A couple of years back, "Social Lead Freak" was a go-to tool. It allowed you to scrape FB content and build out a UID list for Custom Audiences.

That tool doesn't work. Are there any good replacement on the market? Or alternative strategies for building custom audiences looking at competitor Pages etc?

I'm in the same boat... I used to use SLF to creat custom audiences. I need something like that to create audiences from some groups.
