A long time ago I set up a "free" public wifi network for my apartment complex. The captive portal asked them to lease their souls to me for one year, in exchange for unlimited access to the network. It was in the TOS, and they even had to check a box saying "I understand that my immortal soul will be leased". I'm now the proud owner of three human soul-years, and I hope to add to my collection with time 💙
It's probably one of the cringier, edgier things I've done but I'm still so proud that it actually worked. I don't even believe in souls, but I get all kinds of warm fuzzies thinking about it.
