Tracy Tam- promised to repay me. after receiving the money, ignored all my messages and disappeared. Internet

I met her on meetup online group. She texted me one day saying she needed help. So I helped her financially because she claimed to be in an urgent situation. She assured me she would repay the money, now, she completely ignoring all my messages with no responses. Meanwhile, it raises concerns that she may be doing this to others as well. I am not just concerned about my money, but also whether she is taking advantage of other people in a similar way. Please be cautious with such individual.
