If you read all those other threads, you'll notice that none of those scripts get you the actuall font file. That is not possible because the font file is never send to you. All those other threads are about how to get the font _name_. So they do answer your question.
I'm not going to repeat yet again what has been written in those already many threads about this subject, I highly suggest to read them instead. But the bottom line is that you can only get the name with a packet sniffer.
Oh, and you will never be able to completely mimick them because it might well be that the contact is using a font which you don't have on your local PC.
And I find cloners like that not funny but childish, but maybe that's just me
