This is the third SEO tool that has gone under: RankAtom, Wope, and now this. I bought Ubersuggest a while back and it still works. I didn't get it from AppSumo. I'm really disappointed with the business practices of such tools. AppSumo needs to ban SEO tools altogether, as it is degrading user trust. On another note, tools like LancePilot have stopped working too. This platform has become a pump and dump. We users need to wake up and not buy tools if we don't actually use them when they launch.
