After having spoke to a couple of female friends about this I am even more annoyed. One of those friends secured a rape conviction a few years back. There was a fair bit of evidence, but of course the bloke was using stuff such as 'she consented to being restrained to such an extent there were marks weeks later', witnesses heard her shouting no but they were roleplaying as she had a rape fantasy (!) along with others. She reckons, basically if she had to surrender her phone then there would not have been a conviction, because she had some selfies on there that she had sent to a partner once, in underwear and less which would obviously have been used as more proof she consented to the rapist as only virgins are ever actually raped. Was hard enough to get a conviction to start with, and she thinks this would have been just one extra thing to go against her. I don't disagree. And think this is exactly the kind of thing it will be used for. On tinder, clearly looking for sex with randoms so must have consented, selfies, after attention and consents to every man who wants to shove his dick in her clearly, ends messages with x..tease. And so on.
I wish I didn't automatically think this way, but following many many rape cases, I have no other option, as I know how women are treat when raped, and how men get away with horrendous behaviour.
Also have spent a fair amount of time arguing with men who seem to think me saying rape trials should not be focussed on fucking myths, or womens underwear..means I hate men and want to see them locked up for lies 
Hell, one of these men even concluded that it does look like false accusations (where a man actually knows about the accusation, so at arrest stage, which is 6 per year..) really are vanishingly rare, but actually said its better than an extra 1000 rapists go free than those 6 men ever get arrested. Thats the problem in a nutshell tbh, false accusations ruin m,ore lives than rape apparently, and men are more improtant than women. Seems to be the long and short of it.
