I come across ground wires put together like this constantly.. I always at minimum use a crimp (I also placed a crimp here after the pic)

It doesn't look the wires in the pic were twisted too tightly. I can see between them. 110.14(B) says splices are to be made with devices identified for the use

I'd add a reference to:
Quote
250.8 Connection of Grounding and Bonding Equipment.
Grounding conductors and bonding jumpers shall be connected by exothermic welding, listed pressure connectors, listed clamps, or other listed means.

I think a lot of amateurs and professionals alike think "The ground wire doesn't ever do anything, so there is no need for a connector."

Around here, the crimp barrels are pretty popular, but they are often "crimped" incorrectly, that is, just flattened onto the twisted conductors with pliers making for a less than ideal connection.

Not enough sheath in the box?

Where the ground is crimped must extend 6 inches out of the box

That is: 6 inches of free conductor in the box, 3 inches outside the box. (300.14)
