FreeDating Blocked Me After Normal Chats With Two Women

I had two pretty strange conversations on FreeDating recently that made me doubt the site's legitimacy. I talked to two distinct women on July 18 and again on July 22. In all situations, the talks started off properly, with short texts and light introductions. Then, out of the blue and without any warning, both of them blocked me. I wasn't being rude or forceful; I was just wanting to get to know someone. These sudden blocks made me question whether I was really talking to real individuals. Are they real people, or are there a lot of false or inactive profiles on FreeDating? I signed up thinking it would be a good experience, but this trend has made me feel nervous. I'm not worried about the rejections; I'm worried about the lack of openness and the notion that I might have been chatting to fake accounts.
