Q&A With Samuel

How do you start verifying a new online lottery platform?

I begin with a structured checklist covering licensing, company details, and responsible gaming measures. I specifically look for local payment integration like MTN Mobile Money and Airtel Money. After that, I test account creation and key platform features to confirm the claims made on the site.

How do you handle conflicting information during verification?

I document the discrepancy carefully, capture evidence, and contact the platform for clarification. If the issue remains unresolved, I clearly note it so players in Zambia understand the situation before they commit any funds.

What sources do you cross-check during fact-checking?

I rely on official regulator databases, operator disclosures, independent audit reports, and direct platform testing. I also verify that software from providers like Evolution Gaming, Pragmatic Play, and Spribe is authentic and fair. Primary sources always come first, supported by additional verification where needed.

What principle guides your work the most?

Accuracy and transparency. Every claim should be verified, sources should be clear, and readers should always understand how conclusions were reached. Whether checking Bitcoin options or WebMoney transfers, the goal is to provide a clear picture for the user.
