One person, many accounts. See them as one.
Attrelix links new accounts to the ones that came before them, by device, mailbox and card, and returns the cluster with every check.
One script tag and one server call. No card to start.
Why duplicate accounts slip through
Referral bonuses, free tiers, per-account limits and promotions all reward people who open more than one account. Each account looks clean on its own.
The link between them is in details your signup form does not keep: the browser that made them, the mailbox behind different spellings, the card used to verify.
How accounts get linked
Device
The signup page script issues a single-use, 15-minute token for the browser. Accounts made from the same device are linked, and three or ten links weigh more than one.
Mailbox
Gmail dots and plus tags are normalized, so j.doe+7@gmail.com and jdoe@gmail.com count as the same inbox.
Card
Send the card fingerprint from your payment provider and accounts that share one card are linked too.
Questions
Is this browser fingerprinting?
The script reads browser properties to spot automation and to recognize a device across signups on your own site. Data is stored for your account only, and history is kept for the period of your plan.
What about families or offices that share a computer?
A shared device adds risk points, it does not block on its own. You set the review and block thresholds, and you can allowlist your own domains.
Where do I see the clusters?
Every check returns the linked accounts, and the dashboard has a clusters page that groups them.
What does it cost?
1,000 checks a month are free with no card. Paid plans start at $29 a month for 10,000 checks.
