Do DIYers (and the cowboys) have a loop tester and the regs book, do they bother themselves with Zs readings and if the protective device is going to trip in time. Do they bother to get the regs book out and look up graphs liken this.
I'm so glad you asked that, because yes I do possess a loop tester, a CB tester and an insulation tester, and yes I have referred to my regs when I'm unsure.Not only that but I could probably, if pushed, explain the impedance calculation from first principles.

Heres a question for you bonafide sparks. Are you meant to tape up a crimped connection?
No leave them bare.... 
Another beauty from today, starting a loft conversion in a bungalow and this is the original wiring on the ground floor, supposed rewire just before the customer bought it yet no certs.
Took a light fitting down.
brown sleeving on the blue wire and blue sleeving on the brown wire. WTF
Bathroom downlights
I can see at least 7 serious faults in that picture not including the missing screw that I took out.
Amongst all the other faults why would you need to borrow a neutral out of that JB to get something else working (note chopped off brown). I could post pictures like that every day if I wanted to, there are that many bad installations done by DIYers to keep me in work for all eternity. I would say the last 100 or so houses I have been to have had similar problems to that photo, I cant remember the last time I went to one where it was all ok, I would say 75% DIYers and 25% cowboys, either way 99% of houses have dangerous electrics in my opinion.

The earth's are cut off in the old (red/black) wiring, but that was common years ago, wasn't it?What else is wrong? (was the lid missing?)
1. no earth sleeving inside JB,
2.downlights themselves not earthed despite there being an earth terminal
3. earths snipped off as you say so no continuity
4. Connectors just shoved under the floor without an encloseure.
5. Nothing supported or clipped.
6. That snipped off brown wire loose inside the JB and picking up a neutral from this JB for something else, maybe not even on the same circuit is unforgiveable on a reiwre.
7. The connections at the downlights are appalling, you should not be able to see any red or black, it should be sheathed right up to the connections. The way to do it would be to use a small JB thet fits through the hole and a short length of flex that will fit under the cord grip.
