In 2013, she set up an online community called Children-404, which provides a space for teenagers to discuss LGBTI issues, speak about the discrimination they suffer and support each other. Because of her work, Lena has faced homophobic threats, including death threats, and judicial harassment. On 23 January 2015, a court condemned her to an administrative fine of 50,000 rubles (approximatively €650) for “propagating non-traditional sexual relations among minors".
