“What I mean by this is my friend is a new bettor, we sit side by side watching the same games at the same time, and the odds are much worse for me. It will show -100000 on my screen and shows -8000 on my friends screen”
All betting sites have blacklists of customers taking advantage of arbitrage between sites.
Here are some common online betting scams copied from quora.
Fake Betting Sites: Scammers create fake betting websites that appear legitimate but are designed to steal your personal and financial information. Always ensure you’re using reputable and licensed betting sites.
Phishing: Scammers send fraudulent emails or messages claiming to be from legitimate betting sites, asking for your login details, password, or payment information. Never share sensitive information through email or messages.
Too Good to Be True Offers: Scammers may promise guaranteed wins or insider information for a fee. They might also offer bonuses that seem too good to be true. These offers are often designed to take your money without delivering results.
Tipster Scams: Some scammers pose as expert tipsters or handicappers, offering betting tips or predictions for a fee. They may manipulate their records to show past success, but their actual tips might not yield positive results.
Unregulated Casinos: Betting on unregulated or unlicensed casinos can put your money and personal information at risk. Always choose licensed and regulated casinos and sportsbooks.
Rigged Games: In some cases, illegitimate gambling sites may manipulate game outcomes to ensure players lose. Stick to reputable sites that use random number generators and undergo regular audits.
Payment Scams: Scammers may ask for upfront payment to access their “winning system” or betting tips. Legitimate services do not require upfront payments for access to tips.
Match-Fixing Scams: Some scammers claim to have inside information about match-fixing or rigged games and offer to sell this information. This is often a ploy to steal your money.
Identity Theft: Scammers might impersonate betting sites to collect personal information for identity theft. Always ensure you’re on a secure and legitimate site.
Unfair Terms and Conditions: Some betting sites have complex or unfair terms and conditions that make it difficult to withdraw winnings or bonuses. Always read the terms before betting.
