What are the stakes? It's a website with weird captchas and a phone robot that puts you on hold, not a landmine.

Design it well and innocents can be identified quickly and directed to real people who can help them out, as what happened in this video at the end.

sure, but you won't be scamming them, so it's all in fun troll spirit. frankly, i've met some asshats in the real world that i wouldn't mind pulling pranks like this on.
