Common Marketplace Buyer Scams

A real buyer usually wants to inspect the item or pays simply. Watch out for these complex, high-pressure scripts.

The PayID 'Business Upgrade' Scam

The buyer claims they sent the money but you need to pay a 'refund' to upgrade your account to receive it. This is a 100% fraud.

The 'Accidental Overpayment'

A buyer sends a fake receipt showing they paid $500 instead of $50, then urgently asks you to refund the $450 'difference' via a separate app.

The 'Courier Pickup' insurance fee

The buyer says they can't come in person and will send a courier, but you must pay an 'insurance fee' upfront which they claim to have added to the price.

Immediate move to personal chat

The buyer insists on moving the conversation to WhatsApp or SMS immediately to bypass Marketplace's built-in scam detection.

What IsThisSpam checks before you trust a sender

Quick verdicts are useful, but the real value is understanding why something looks safe, uncertain, or risky.

Brand-new Buyer Profile

Profiles created in the last few months with no history or friends are frequently used by automated scam bots.

Generic 'Is this available?' bots

Instant replies that use the exact title of your listing but don't ask any specific questions about the item's condition or location.

Pressure for 'Email' addresses

Buyers don't need your email for a standard marketplace deal. They only want it to send you a fake PayPal or PayID alert.

Refusal to pay in cash on pickup

If they are local but refuse to pay cash and insist on a 'bank transfer' with a 'receipt' they'll show you, be extremely careful.
