If possible, start by using a clean browser profile and a proxy when creating new accounts. Regardless of how many accounts you create, try to ensure that their account styles, creation times, and activity patterns are inconsistent. Use anti-detection browsers that support cookie import, as well as products that offer free trials or a permanently free tier.
Of course, the most important factor is your account behavior. Avoid using simple, repetitive automation tools whenever possible, as they are easily flagged by Quora as bots. Once you start triggering account verification frequently, your account is at risk.
