That’s actually an interesting question. I’ll assume that you mean that someone plays a character, like how the youtubers do it, but they’re not the same way in person. I don’t think that has anything to do with whether they’re dating someone or not, but let’s think about this…

I would say that there are probably two situations that fall under the category you bring up. 1) the online persona is more outgoing than the IRL persona, or 2) the online persona is more docile than the IRL persona.

For women, if the online persona is more docile/subdued, that’s not going to be much of a problem, because people will just perceive her as boring or dull. Once the meet her IRL, they’ll get to experience her off-screen personality, and they’re realize she’s a cool chick (or crazy, or whatever).

OTOH, if her online persona is way more outgoing, a lot of her fans are going to latch onto that and perceive that they have actual “chances” with her. Of course, this leads to obsession & stalking, which, most times, isn’t a good thing.

Of course, there are also several types of “outgoing”. There’s “Kooky” outgoing, like she’s always doing skits or playing herself in fast forward or bouncing off the walls in her videos. There’s also “Sexy” outgoing, which is more of the obsession-inducer.

It’s always a good idea for women to consider how their fans might perceive their online character and then attempt to relate to them as that character IRL.

Is that what you were talking about?
