Doing it right indeed means a slower tool per account to be scraped that replicates human randomness while browsing the pages.
anyhow, The law of automation is if you can do it manually there is always a way to automate.
ClonBrowser i imagine brings you indeed on a good way for semi automatic.
Perhaps tools like: TinyTask , Or a more advanced: Sikulix (Both Free!) can help you automate the rest of the process using ClonBrowser. (Learning curve is very low if one has motivation to save up time

)
If you do have a business around this and make money of scraping these details itl be worth connecting with a programmer to invest and free up some of you precious time:
While at the moment i am finishing a google ranking bot with human behavior plans for a couple of BHW members.
The similarity in how to beat youtube on a consistent base seems similar to the ranking. And is definitely a topic ill be visiting sooner or later regarding its view botting in a good way, Slow and with a growth plan, As with google.
A quick google about youtube scraping also showed me no results for a trusty tool that can handle a good amount of volume for legit youtube views by bot, and as a added the info about the channels.
Atleast what i found, or read about the process they use.
Always glad to open a conversation about how much of those happiness one can spare for some free time
The pay per catchpa is also something i did not read in ages, What scraping business asks for a pay per scrape?
