When I buy Instagram Accounts I like to change the E-mail for security reasons, My questions is now because i have a lot of Websites and my own Domains, how Instagram would look at this when I create my own mails with my Domain for thousands of Accounts would that be a problem because I don’t use any big provider?
I’ve personally found that when I created 10/20 accounts all with the same domain within the email they required a lot more ‘warming up’ had to do a couple confirmations holding the instagram username up on a piece of paper.
I’ve just stuck with gmails since then and had no issues.
