Is it insane to make plans to move in with someone that you only know over the internet?

My best friend has been talking and in a relationship with someone online who lives across the country. They havent ever met physically, but have been intimate over the phone and internet I guess. She and her husband are getting a divorce and she is currently still in the same house with him but plans to get her own place she just has to wait until her financial situation stabilizes. But she is making plans for this man who is unemployed currently to move out to her state and live together, with her children. She says they are in love and over the year have gotten to know each others ins and outs by talking for hours a day. I told her maybe instead of talking for hours a day he should have been looking for a job and paying his way to come see her and get to know her.. I am worried that she is making a huge mistake and is going to be stuck with someone she really knows nothing about. Do you think I am right?
