I'm curious about this too because virtually every "APK DOWNLOAD" site and non-official APK provider for it embeds malware/adware of some sort. I am wondering how many are actually using a good build and how many are just getting misled by the first result they find.
I mean these sorts apps being taken down and easily replaced are ripe for have malware sneakily inserted into the replaced version because there’s suddenly huge demand for the app.
