Yes. How many? Generally, there's not enough time in 1 day to automate more than 3/4 accounts on 1 phone if they're doing decent number of actions.
Theoretically kind of unlimited. The only limiting factor is that, how powerful is the PC (ram, cpu, etc.).
I've seen people automating 90 mobiles via ADB from a single PC with 32GB ram and some powerful CPU (I don't remember the CPU name exactly).
Yes, It is completely undetectable to apps. Like whether they are getting run by a real human or getting automated.
(Automation via ADB sends device input actions (touch/tap/swipe) directly to the android OS (as if they are sent by the real touchscreen)
and Android OS passes those inputs to the app.
Just like how your (real human) touch/tap/swipe on the real touchscreen sends the input actions to the Android OS and then Android OS passes those input actions to the App.
So, for the app, both are exactly the same, as, it is only talking to Android OS.)
It is as safe as if you hire some person to do the exact same Actions.
But do note that even real humans will get action blocks if they do too many actions. So, just use the settings accodingly.
Yes, it's basically completed, It's in testing phase now.
There's no need for scraping. I only put things into place what and how a normal human would do.
