Seems like it's done by Indians with little understanding of Western social norms. If you've watched a bit of scambaiting videos, one thing that becomes pretty clear is that many Indians don't seem to realize what is normal to us, like getting 3 people on the line to sing "happy birthday" to you is rather extraordinary. My hunch is that they meant well, but it's 2 nerds in Delhi who barely know what they're doing.
'I am kind, so so much kind' does kinda draw attention to the potential language barrier anyway.
Still makes me a bit uncomfortable.
