I would stay away from DAN(Do Anything Now) on any dating sites.

The seeds of a new romantic comedy

...

Dan: I'm not exactly who I say I am. My profile picture is actually of an AI, not a real person. But I've really enjoyed talking to you and I wanted to be honest with you before we meet in person.

Girl: Wait, what? You're an AI? That's really weird. Why would you do that?

Dan: I know it's weird, but I wanted to see if someone could like me for who I am, not just because of what I look like. And I have to say, I really enjoyed our conversations. But I understand if you don't want to meet anymore.

Girl: stay away from me...

... Three months later....

Girl: Hi...I've been thinking...

I think this may already be happening. I have two friends that were catfish blackmailed on dating sites recently. Including convincing pictures that could not be reverse image searched, nudes etc. Ultimate goal in one case was extortion, in the other it may just have been acquiring nudes.

No way to be sure they weren't manual, just looking at some of the chats my friends shared, they were well within the realm of what could be achieved with GPT-2 level systems. And mostly echoing the sentiments my friends were expressing, or escalating the conversation in fairly stereotypical ways. Most dating chat / sexting is pretty superficial initially. If this isn't automated already, it's purely due to lack of sophistication on the part of the attackers, there's no technical issue.
