An electronic version of sending back a bunch of blank papers in the
postpaid envelope that comes with credit card offers.

I used to have a couple hundred small flat pieces of some kind of thin
steel.
I'd put those in the envelopes so they'd have to pay extra postage.
I still send them back (though I don't have any more of the steel). I
write "remove me or keep paying postage" on the offers.
