Absolutely anecdotal evidence but I have noticed that men prefer generally their porn visual while the women in written form. There is reason why the slashfic writers and consumers are mostly female.
I am going to go out on a limb and say that there is more population exposure(and thus consumption) of novels such as 50 shades vs any yaoi. Why is there more exposure? Because it is delivered what women want(thrilling erotica)Is it just because Yaoi hasn't broken out into mainstream? Perhaps, but there are always erotic novels featuring a handsome men at the checkout counter.
Venomsnake mentioned slash specifically -- yaoi is much more mainstream than slash, especially in Asia.
If you want to talk about more mainstream material, particularly what appears at the checkout counter, one confounding factor is that written material in general is less restricted and stigmatized than visual material. There is no ESRB or movie ratings board for books, and parents who would never allow their children to watch an extremely violent movie or a porno will let them read absolutely anything at all. So written pornography can be put out at the checkout counter in a way that visual pornography can't. Women who want visual porn get it online or on late-night TV.
You can't. You just transfer a blob of random radio noise data to a server in Canada.
I have always thought that every encryption system must have constant transmission up/downstream rates no matter if you are sending or receiving any data. You connect and begin sending 1Mbit every second. And it will just filter the nonsense packets for when you send receive real data.
It doesn't have to be a perfect technical solution. They can outlaw VPNs - they just make it a law. Enforcement will be selective, although I guess for some well-known handshakes they could perform blocking.
If they detect something like what you described, they can flag your account, ask for justification, use as "evidence", etc.
