Where this data comes from

Official, public sources only

Today we use a single source: the CERT Polska Warning List — a public register of domains used for phishing and fraud (including fake investments), maintained by the incident response team at NASK. We will clearly label any additional sources (e.g. KNF warnings) once we connect them.

A fact, not a verdict

We show the fact of a listing — with the source name and the sync date. Entries are decided by the list operator (CERT Polska), not by us. A domain owner can appeal directly with the operator (the procedure is described on the list's website).

Limitations

A domain being absent from the lists does not mean the site is safe — scammers register new domains faster than anyone can catalogue them. An entry covers the domain, not each subpage individually. We sync the lists once a day, and entries removed by the operator may remain here with a date annotation.
