I just used temp-number.com to receive a verification code (no cell towers where I live). I was shocked to see that someone had sent their Bitcoin wallet info to the service.
I got their username, password and verification code. Their account is worth over 60BTC. That’s over $2,000,000.
No I did not steal from them, but holy cow I can’t believe how incredibly stupid that is.
So be mindful when using these, they’re fully open to the public to read.
For those curious, this is in fact the account I found.
