Protection of children against sexual exploitation, particularly against exploitation in cyberspace, constitutes one of the most burning issues of the modern world. The Internet is frequently used as the beginning of the road to sexually exploiting a child, and as way of earning the child’s trust and gaining physical access to them. Unfortunately, the COVID-19 pandemic and isolation resulting from it brought with them substantial threats, also in this area, whose effects will be long-term. What was observed during the pandemic was not only an increase in online traffic related to the distribution of child pornography, but also a definite increase in behaviours that may be classified as grooming. It is sometimes considered that grooming is the basic method leading to child sexual exploitation, or even its immanent feature. Relatedly, what becomes an important issue is an analysis of legal regulations that concern grooming in cyberspace, and an attempt to answer the question whether the scope and level of protection provided to children by Polish criminal law are sufficient.
