I've had so many in the past few days that I've merged them into a "highlight" reel.

1. 1:15 ish, pass on the number of people.
2. 41 minutes, 3 people (I think)
3. 10 minutes, 1 person

Standard stuff for most, `eventvwr`/`msconfig`, get TeamViewer, run a "scan" with `tree` whilst they type some nonsense about broken internet security, router needing replacement and me eligible for a refund.

The interesting thing is that most of the scammers now ask you to remote into their machine, as after a number of outgoing connection requests TeamViewer limits the connection time to 5 minutes: not ideal if you need longer than that to explain the "scan" and get the victim's bank details.

I only discovered this timeout after I connected to the first scammers, and the connection kept dropping, lengthening the call.
They hung up after I tried to log into my bank account with the username "HiScammers!"

Second lot were also standard, until I asked them if their scam wasn't working; protip, stopping `explorer.exe` and `iexplore.exe` is not going to inconvenience me, and no, you don't know what a virtual machine is.

Third didn't even get as far as connecting, claimed to be a follow up call from Friday, as they needed to finish the work.
They tried connecting to me, but TeamViewers new "This is a scam" warning appeared (I'd like to take credit for this, but I'm guessing TeamViewer haven't yet reviewed my report).
They did swear at me when I asked if their scam hadn't worked.

So, scores:

1. 2/10
2. 2/10
3. 3/10

Wouldn't use again.
