We use Shopify’s Fraud Filter app to block IP’s, addresses and names. Works farely well :- https://apps.shopify.com/fraud-filter
Topic summary
Recurring unwanted traffic is reported, frequently from Ashburn, US, with a visitor name ending in “Musterman.” The merchant asks about blocking a specific IP and notes the visitor may be using a VPN.
Recommended mitigations:
- Use Shopify’s Fraud Filter app to block IPs, addresses, and names; community members report it works fairly well.
- Consider geolocation/IP blocking apps; “IP Blocker & Country Redirect” is highlighted as a promising option with positive reviews and a 7‑day trial.
Related development: Another merchant reports Ashburn-origin attempts to place small (~$10) orders using other people’s credit cards, suggesting possible card testing.
Outcomes and status:
- No confirmed resolution from the original poster.
- Actionable next steps are to install Fraud Filter and/or an IP blocking/redirect app.
- Open questions remain about effectiveness against visitors using VPNs and whether these measures stopped the specific Ashburn activity.
