THE PROBLEM
Open registration helps communities grow, but low-quality and abusive accounts can create moderation work before they contribute anything useful. Disposable inboxes, placeholder-style identities, questionable domains, and unusual network context can justify additional scrutiny before member-facing access is granted.
Low-quality accounts can enter communities solely to post links, send unwanted messages, create throwaway profiles, or consume moderation attention.
Temporary and disposable inboxes can make short-lived account creation inexpensive and difficult to manage.
Without useful registration context, moderators may only discover problematic accounts after posting, messaging, or other member-facing activity has already begun.
Posting, messaging, links, profile creation, and other community privileges can create moderation cost when granted immediately to every new account.
HOW IT HELPS
Add Signup Risk API during registration before your application enables posting, messaging, links, profile creation, or other community privileges.
Send the email address and optionally include the user’s name and signup IP for additional context.
Signup Risk API evaluates disposable-email usage, domain infrastructure, provider type, role addresses, typo domains, synthetic identity patterns, name alignment, and optional IP reputation.
Use the allow, review, or block recommendation to grant normal access, introduce additional verification or reduced permissions, or stop very-high-risk registrations according to your community policy.
RISK CHECKS
Signup Risk API evaluates registration context across key risk checks to surface objective evidence for your access policy.
Detect confirmed, likely, and suspicious disposable-email usage that can make short-lived account creation inexpensive.
Identify placeholder-style email patterns and other synthetic registration characteristics that may justify additional scrutiny when combined with other evidence.
When IP context is available, evaluate network characteristics such as datacenter, VPN, proxy, or Tor usage as one part of the broader registration decision.
Evaluate domain existence and mail-related DNS infrastructure while distinguishing authoritative findings from temporary lookup failures.
Classify common consumer, business, education, government, and unknown email providers without treating provider type alone as proof of abuse.
When a name is supplied, evaluate how well it aligns with the email address and whether the supplied identity appears plausible.
Raw signup IPs are not returned in the API response.
DECISIONING
Signup Risk API complements CAPTCHA, bot protection, content moderation, behavioral detection, and human moderation. It evaluates the registration layer before those systems have post-signup behavior or content to analyze.
Grant normal community access when the available evidence contains few meaningful risk factors.
Apply selective friction such as email confirmation, CAPTCHA, delayed posting, reduced permissions, or moderator review when the evidence is uncertain.
Stop very-high-risk registrations before posting, messaging, or other member-facing privileges are enabled.
WORKFLOW
User submits the registration form
Your backend sends email, optional name, and optional signup IP
Signup Risk API returns the decision, checks, explanation, and metadata
Your application applies its community-access policy
Your application grants normal access, limited access, or no access
Use the recommendation directly for a simple registration gate, or inspect the check-level evidence to build custom moderation and permission workflows.
OUTCOMES
The goal is not to treat every unusual registration as abusive. It is to avoid granting full community privileges blindly when the available signup evidence justifies additional friction or reduced access.
A low-quality account may be free to create, but it is not free to moderate. Spam cleanup, reports, review queues, member complaints, and moderator attention all have real operational cost. Signup Risk API helps you make the access decision before that cost reaches the moderation team.
Evaluate registrations before low-quality accounts can begin posting, messaging, creating profiles, or consuming moderator attention.
Keep lower-risk members moving while reserving email confirmation, CAPTCHA, reduced permissions, or review for registrations with stronger risk factors.
Use registration risk to decide when new accounts should receive normal posting, messaging, linking, or profile privileges.
Signup Risk API recommends allow, review, or block; your community decides what those outcomes mean for permissions, verification, and onboarding.
Signup Risk API evaluates the registration layer. CAPTCHA, bot protection, content moderation, behavioral detection, abuse reporting, and human moderation can continue handling the post-signup controls they are designed for.
Use Signup Risk API alongside your existing authentication, CAPTCHA, bot-protection, and moderation stack (such as Clerk, Auth0, Supabase, Firebase, Cognito, or custom auth). Call it from your backend during registration before posting, messaging, or other member-facing privileges are enabled.
