Why there are rules
GSG exists so buyer and seller can operate safely. That only works if every transaction stays inside the platform: escrow, KYC, disputes. The chat is for coordinating the trade, not for moving it elsewhere.
What you CANNOT share
These rules are NON-NEGOTIABLE:
- ❌ Phone numbers (mobile, landline, WhatsApp).
- ❌ Personal emails.
- ❌ IBAN or bank details.
- ❌ External links (social media, other marketplaces, personal sites).
- ❌ Alternative messaging apps (Telegram, Signal, Discord, etc.).
- ❌ Any attempt to arrange payment outside escrow.
What happens if you try
The auto-filter does three things:
- The message is blocked before sending. The other party never sees it.
- It's logged in moderation with full content.
- A fraud alert is opened automatically. Repeat offenders get suspended.
Why the hard rule
Any transaction outside GSG loses:
- ✗ Escrow (your money has no protection).
- ✗ Disputes (no arbiter).
- ✗ Legal traceability.
- ✗ GSG-contracted shipping insurance.
Common scams: the "seller" vanishes after being paid; the "buyer" claims non-delivery with no carrier evidence. GSG can't help in either case.
