I didn't get much of it at all, but OP did just say a whole load of stuff that made Sam sound a bit like a stalker really. I think that was a definite attempt to discredit the testimony she gave.
Yep, and I find that kind of thing really unpleasant .. people do that kind of thing on the internet all the time nowadays to try and discredit someone .. I've had it done to me and it is deeply unpleasant. The people who do it know though that once they have planted the seed of doubt in other people's minds, then those people will always have in the back of their minds that that person is a stalker. It's quite a common thing nowadays, on the internet, to be accused of being a stalker .. I've known loads of other people have it happen to them too. There is no way of proving it one way or the other, unless it is investigated by the police and a stalker is actually traced back to the actual person doing it.
There are millions of people out there in internetland, and that stalker could have been anyone.
