I sometimes do this too, just for entertainment purposes. I once got invited to open a Turkish bank account so I could receive a large sum of money, I apparently inherited from some dead uncle. I once introduced myself as 'Gofu Kurself', thinking that would be obvious enough for them to know that I wasn't falling for it. They sent me all sort of guides on how to set up the bank account, even sending me some fake legal documents I had to sign. Long story short, they weren't happy when they found out that I was fucking with them.
