Most guides only tell you where to bet. We think it matters just as much to tell you where not to. SportsWhizz has a firm licensed-operators-only policy — we never feature a bookmaker without a verifiable gambling licence. Rather than smear specific brands, this page explains the categories of operator to avoid, the red flags to spot one yourself, and exactly how we vet. Where a book we do feature carries a caveat (a grey-market lineage or a weaker licence), we flag it honestly in its review.
Unlicensed operators
⚠ No verifiable gambling licence - A company registration, a “Costa Rica” data-processing entry or a payment-processor listing is NOT a gambling licence. If you cannot find a real licence — MGA, UKGC, a Curaçao licence with a verifiable number, Kahnawake or a national regulator — and confirm it on the regulator’s own register, treat the operator as unlicensed.
- Without a licensing authority there is no ADR, no complaints route and effectively no recourse if a bet is voided or a withdrawal is withheld. We never feature operators like this.
Grey-market clones (1xBet / 22Bet-family and lookalikes)
⚠ Mixed record · read the fine print - A number of near-identical “white-label” sportsbooks share the same underlying engine and marketing playbook. Some hold a real (if weak) licence; many spun-up clones do not. The brand looking huge is not evidence it is safe.
- Where we do feature a book that shares this lineage, we say so plainly and flag it as a con in the review — because ownership transparency and dispute history matter. If a clone has no verifiable licence at all, avoid it.
Dead, expired or “licence-shuffled” Curaçao books
⚠ Accountability red flag - Under the new Curaçao LOK regime, older master-licence sublicences are being phased out. Operators that keep moving brands between licence vehicles — or whose licensor has been dissolved — are avoiding accountability.
- Always click the licence seal in the footer: it should link to a live, in-date certificate. A dead link, a screenshot-only seal or an expired number is a reason to walk away.
Anjouan-only books with no real recourse
⚠ Weak player protection - An Anjouan (Comoros) licence offers far weaker player protection than the MGA or UKGC, and its standing has been questioned. A book operating on Anjouan alone gives you little practical dispute recourse.
- This is not an automatic blacklist — but we down-weight it heavily, insist on payout evidence, and tell you to lean on independent mediators. Prefer books with a stronger primary licence where you can.
No payout proof / withheld-withdrawal patterns
⚠ The clearest warning sign - Repeated “under review” for weeks, fresh KYC demands only after you win, shifting bonus terms, or confiscated winnings are the single biggest red flag. Patterns matter more than one bad review.
- We track payout complaints and dock a book’s score for verified cases. An operator with a stack of unresolved withheld-payout reports and no evidence of paying will not be recommended.
Tipster & “fixed-match” prediction scams
⚠ Not a bookmaker problem — a scam - Anyone selling “guaranteed winners”, VIP tips, or access to “fixed matches” is running a scam, full stop. No one can guarantee a sports result, and SportsWhizz never publishes tips or predictions.
- These schemes often funnel you toward an unlicensed book they’re paid to promote. Ignore them and stick to licensed operators and your own research. See our tipster-scam guide.
You don't need us to vet every site. These are the warning signs we use — any one of them is a reason to be cautious; two or more, walk away.
No real gambling licenceA company or data registration is not a gambling licence. Look for MGA, UKGC, a Curaçao licence with a verifiable number, or a national regulator — and check it on the regulator’s own register.
Licence-shuffling or dead sealsBooks that move brands between licence vehicles, or show a footer seal that doesn’t link to a live certificate, are a red flag for avoiding accountability.
“Not on GAMSTOP” marketingOperators that advertise to self-excluded bettors are deliberately targeting vulnerable people. Walk away.
Withheld or endlessly-delayed withdrawalsWeeks of “pending”, repeated KYC after a win, or confiscated winnings are the clearest sign a book won’t pay.
Offers that sound too goodEnormous free bets or match percentages with buried high turnover, tiny max-stake caps, min-odds traps and short clocks are designed so you never actually cash out.
No responsible-gambling toolsA legitimate book offers deposit limits, self-exclusion and links to help organisations. Their absence is telling.

We never publish tips or predictions. This page describes general categories and reflects our honest vetting standards; where we name a caveat about a specific book, it appears in that book's review.
