All famous people sometimes attract attention that they'd rather not receive. In the case of Lukyanova, that attention has sometimes been violent. She was assaulted in her home in Odessa in 2014.
Fortunately, a neighbor was able to come to her aid before any lasting damage was done, but she was still taken to hospital with severe cuts and bruises. It later transpired that her attacker had been threatening her through the mail and the internet for more than two years.
