Which app icon is in the picture?

Is it me or does this read like an advertisement?

Knodel1958, not to mention it's a cesspool for scammers that should be closed down, if they can't moderate or self-regulate properly!

For me, Telegram is free long distance calling. I talk to my language partner in Central America several times a week. I wasn't aware of any problems with scammers.

It was really very so fun. Send.
