Since you are a Shopify partner, these are automated account creations and are safe to remove with bulk customer actions or flow rules. These artificially boost metrics and, if synced to marketing tools, can impact email deliverability. Add reCAPTCHA on customer accounts, require email verification, and block disposable domains to stop future bot signups.
Yes, it is safe to delete those customer records.They aren’t dangerous but clutter data and marketing metrics.
You already did one smart thing by delisting the targeted product. Otherthings can be done: add CAPTCHA to forms,avoid unnecessary signup forms,monitor email marketing tools and avoid auto-syncing new customers into campaigns and disable or limit customer accounts.
Hey! I’d recommend a customer blacklist app. This will allow you to block that bad customer’s email from ever coming back. The one that I use is called Blox. It actually connects any new information related to that same person, so you’re not having to continually re-block each new email the same person creates. Hopefully that helps you out!
