How do You find all links pointing to a domain?
 

I used to use Yahoo Site Explorer but it doesn't seem to work.
Google is shit for this
ahrefs is ok but it's not free and I'm not 100% sure I trust it.

Something like SEOmoz will give you a better list but it's 99 a month for the cheapest plan. I haven't seen a free one that will show you a good list.

aHREFs works fine for me.
