copper is insanely expensive ....
these days, people ( at least here in the usa )
are stealing copper pipe, wires and conduit
out of houses when people are away on vacation,
vacant buildings and even electrical sub stations, to
sell the copper for $$
i documented a building that was to be demolished a few years back, and thieves
were stealing copper out of it weekly ( thousands of dollars worth!).
on the last day i was there, i was photographing the exterior
( from a high vantage point to show the parapet and clearstory monitor windows &C )
there was a group of 5 people breaking into the building through the rooftop windows.
(you couldn't see them from the street ... )
aside from the excessive cost of copper, one of the other problems is, once you get your sludge
and you scrape the silver off of the copper and dry it out, what do you do with it ?
and how do you know that your copper plated all the silver out of your blix ?
part of the problem with home-brew alternatives is they are not
as efficient as a mechanism that is made specifically for this purpose.
they are less expensive and may work, but you may have some loose ends to tie.
sometimes just taking the spent chemistry to the waste recovery day is the
most feasible, inexpensive and hassle free solution ..
Is the fix "clean" enough of silver after using any of these home brew systems including steel wool and magnets that you don't have to take them to haz waste anyway?

the laws are different no matter where you go,
so it is best to find out in your own location what needs to be done.
