In 2013, she set up an online community on Facebook and on the social networking site VK named Children-404, which provides a space for teenagers to discuss LGBTI issues and support each other.

The Project’s Facebook and VK pages (entitled "Children-404") publish letters from Russian LGBT teenagers in which they talk about the problems they face in their lives due to homophobic people around them - friends, relatives, classmates, teachers, and others.

Meanwhile, one family in twenty has an LGBT-child in it, and those children are society’s invisible "Children-404".Lena Klimova, a young journalist from Ekaterinburg, published a series of articles critical of the parliamentary bills against "propaganda of homosexuality".

Within under two weeks Klimova had received over a hundred e-mail responses, and that is what made her resolve to create an online support project for LGBT teens.

On 5 July 2013 the "Children-404" Project supported the family of Marcel Neergaard, an eleven-year-old gay boy from Tennessee, who had become well known in his home country for his success in combating homophobia.

On 21 February 2014, the charges were dropped after the court ruled in consultation with a mental health professional that the page "helps teenagers exploring their sexuality to deal with difficult emotional issues and other problems that they may encounter", and did not constitute "propaganda" under the law.

Mizulina: Information that is explanatory, or descriptive, or which does not call for anything, which is not provocative, which doesn’t depict non-traditional sexual relations, is not propaganda, it can be legally accessed by teens.
