For a start, they provide no support to the wires, so any movement is transferred to the vulnerable point where the copper is crushed under the screw. They are almost impossible to seal against moisture.
The only times they are acceptable are as a quick-fix until a better join can be made, or with the addition of ferrules to terminate the wires.
