Several things not all that great with this......but certainly we've all probably seen worse.
Disregarding the loose and unauthorized carabiner, the messenger wire for the service drop is tied to the porcelain insulator in such a way that it won't swivel when wind sways it, instead the messenger puts strain on the insulator behind the proper slot, 90 degrees out of whack....minor, but not how the insulator is designed to be tied to.
I've seen several power companies use the Burndy / Blackburn-type crimps to lengthen or repair a wire, and that's OK if the right size is used and if they are AL-CU alloy, some with built-in NO-ox paste under the push-on cap, as most overhead service drop conductors are aluminum with a galvanized steel messenger and the building conductors are copper.
And we all know how sturdy a fascia board is......
