How to effectively use scraping sources??

hello guys! I need some help!

I want to build 100 accounts and more that would be pushing my main page but I don’t know how to manage scraping sources. Do i need to find one good scraping source for each account? Is there some other easier way? I have seen people build 500 childsccounts but I’m not sure if they handpick 500 sources.
Any help would be appreciated!
Thanks!

Most people have a group of sources that they scrape, not necessarily one per account since the content doesn't have to be unique on all of those accounts.

Do you mean for example finding 20-30 sources and let all account scrape from all these sources?
