Re: "...some parts are really very dangerous..."
"...and some parts are just a bit sketchy."
Agree mostly, have an upvote, but a really smart group with a powerful script will get more action if they can get their trap set on a hugely popular site -- as has been done on Forbes and Huffington Post, 'monsgst others. So the "sketchy" concept here should include just a few expert muggers with full-auto guns lurking in "safe" neighborhoods like Bexley.
For a long time, the wise have been saying that visiting dodgy sites and downloading promiscuously risks infection. And so it does. But in these dank days, drive-by infections can be had from completely innocuous websites.
As one of the careful-and-safe, I try to remember not to blame the victim.
