To my knowledge, purchasing aged accounts from a trustworthy seller would be the best approach. Keep in mind that an aged account comes with cookies, so inquire about the cookies as well. Also, utilize an antidetect software that offers an import cookie feature and add a proxy with an IP that corresponds to the account's login location. By following this method, the chances of suspended accounts will be reduced.
Now I'm using this method with Hidemyacc anti+ brightdata proxy and accounts from my country seller. Work really well.
