Only legally accessible sources of information and documents are allowed for research. To search for information, OSINT techniques for working with publicly available information, lawyer requests, as well as official requests from authorized bodies can be used.
The information received can be confirmed by officially certified documents that served as the basis for providing this or that information or corresponding conclusions.
In some cases, providing a source of information is impossible. In this case, it is allowed to issue an impersonal expert opinion.
Practices of corruption or bribery to gain access to closed sources of information that constitute banking, tax or other secrets are excluded.
