This should be illegal. You gave them an email box and money. You sent the spam. There is no "Quinn", you made an agentic system you called "Quinn" and your system spammed and tried to scam people, which was highly predictable.
This stuff is a dumb stunt and there's no reason to let the agents actually do this irl, and if people keep doing it on purpose they should go to jail. You're running an agentic Jackass skit pretending to be a research lab.
