Working with multiple accounts, I’ve found public connections work best. Libraries, universities, and malls have IPs Google sees as “normal” since tons of different people use them daily. You can connect to these networks from home if they’re open, or use apps that share legit connections. Browser history matters too - before creating new accounts, I browse regular sites like news or YouTube for a few minutes. Makes it look like real human activity. Google checks your behavior before registration, not just during signup. Here’s something nobody talks about: don’t use recovery emails already linked to other Gmail accounts. That instantly connects them in their system.
