What is Sts?
Sts.ch is in our scam category. This label is used for domains linked to deceptive offers, non-fulfillment after payment, or data collection under false pretenses.
What users usually see: copied branding, fake trust badges, edited reviews, and checkout pressure (timers, "last items", "verify payment"). These signals are easy to fake and should not be treated as proof of legitimacy.
Safety step: do not send documents, card photos, or wallet transfers. If a payment was already made, contact your bank/provider immediately and preserve receipts, URLs, and message screenshots.
This domain was registered May 19, 1996 at 9:00 PM through the company Gandi SAS
