Hello.
1. Increasing Difficulty with Mainstream Providers like Gmail, Yahoo, Outlook, iCloud
Major providers have tightened registration significantly to combat fraud, including carding. Google (Gmail), Microsoft (Outlook), and Apple (iCloud) now frequently require phone number verification, especially for new accounts, multiple creations from the same IP, or suspicious patterns. This links the email to a real phone, making it harder for fraudsters to mass-create anonymous accounts.
In carding:
- Carders dislike this because phone verification can tie accounts to traceable numbers (e.g., via SMS providers or virtual numbers that get blacklisted).
- It reduces the "supply" of fresh, anonymous emails for testing cards or creating mule accounts.
- Result: Carders often turn to alternatives that skip phone checks, or use farmed/bought accounts.
From anti-fraud view: This is intentional. Phone requirements raise the barrier for bots and fraud rings, lowering overall risk scores for emails from these providers. Accounts from Gmail/Outlook are often seen as slightly lower risk because creation friction weeds out casual abusers.
2. Proton Mail's Easier Registration and Its Impact on Fraud Risk (Including "Fraud Value")
Proton Mail remains easier to register: typically just username, password, and CAPTCHA — no mandatory phone or alternate email. This privacy-by-design approach (end-to-end encryption, Swiss jurisdiction) makes it appealing for legitimate users wanting anonymity.
In carding context:
- Higher "fraud value" for fraudsters: Easier creation means quicker setup of multiple fresh accounts without phone traces. Privacy features (encryption, no logs of content) make it harder for law enforcement or platforms to subpoena readable data. In underground communities, privacy-focused emails like Proton are preferred over phone-linked ones for operations needing separation from real identity.
- However, this attractiveness is limited: Proton aggressively monitors for abuse. They use algorithms to detect mass registrations, spam, or fraudulent patterns and disable accounts quickly — often automatically. This protects their domain reputation but can lock out users mid-operation if flagged (e.g., rapid signups on gambling/crypto sites).
In anti-fraud systems:
- No broad increase in fraud risk scoring: Reputable detection tools (e.g., Scamalytics rates Proton as "potentially low fraud risk"). Proton is not classified as disposable/temporary (it's not on major burner blacklists; efforts exist to remove it from such lists). Abuse rates are claimed to be comparable to or lower than Gmail/Yahoo due to proactive bans.
- Some increase in scrutiny or blocks: Anecdotally, certain platforms (e.g., government services, some banks, gaming sites, or e-commerce) block or flag Proton domains during registration/transactions. Reasons include past abuse patterns or association with privacy users (which overlaps with some fraudsters). Examples include occasional flagging as "temporary-like" or custom rules in fraud engines. Proton even has a support process to contact blocking sites and explain their legitimacy.
- Net effect: Slight elevation in perceived risk for conservative systems, but not a major jump. It's still treated as mainstream/low-risk overall — far better than true disposables (e.g., Temp-Mail, Guerrilla Mail), which are heavily blacklisted and auto-reject.
3. Are Mainstream Providers (Gmail, Yahoo, Outlook, iCloud, Proton, etc.) Treated the Same?
Mostly yes, but with nuances in carding/anti-fraud:
- Similar low-risk treatment overall: All are established providers with good domain reputations. They pass most automated checks and aren't blacklisted like disposables. Fraud scores depend more on other factors: email age (older = lower risk), activity history, linkage to phone/IP, and transaction behavior.
- Differences:
- Gmail/Outlook/Yahoo/iCloud: Often viewed as marginally safer signals because stricter creation (phone requirement) reduces abuse volume. They benefit from being "default" choices for average users.
- Proton: Comparable in most fraud tools, but faces occasional extra friction — e.g., blocks on specific sites or higher manual review triggers due to privacy appeal attracting a subset of bad actors. Not a universal penalty; many platforms accept it fine.
- In carding practice: Fraudsters might prefer Proton (or similar like Tutanota) for anonymity/value, but risk account disablement. Gmail/etc. are harder to acquire fresh but more likely to pass checks.
- Anti-fraud conclusion: No dramatic difference. Using any of these won't inherently spike risk scores significantly. The biggest risks come from disposable domains, new/free hosts with poor reputation (e.g., certain Russian/.xyz providers), or mismatched signals (e.g., new Proton email + foreign IP + high-value transaction).
Summary in Carding/Anti-Fraud Balance: Proton's easier registration does increase its "value" to fraudsters somewhat (better for anonymous, quick setups), but their strong anti-abuse measures and low domain risk keep it from being broadly penalized. It's not "the same" as Gmail in every system — Proton can hit rare blocks or flags — but the difference is minor for most uses. For highest pass rates in strict environments (e.g., banking, high-value e-commerce), Gmail/Outlook might edge out slightly due to built-in barriers. All mainstream options are vastly superior to disposables for avoiding detection. Anti-fraud evolves constantly, so platform-specific rules matter most.
