Yeah. I was going through a short phase where I was loaning money on /r/borrow. I don't make much money at all, but I'm good at saving and I like to help people, so I figured why not.
I loaned a guy $40 on r/borrow and never got that back. And the amount of money is so insignificant that losing the $40 didn't even bother me, it was the fact that someone would screw someone out of only $40 that got to me (saying he was sick and needed money for medicine or something; can't remember exactly).
After that and then this, I'm definitely done loaning people money over the internet. I haven't lost faith in humanity or anything, but I'm obviously done doing this kind of thing. I'll openly admit that I'm a little too trusting when it comes to stuff like this, so no need for anyone to remind me, but yeah.
When it comes down to it, if someone would stoop this low, they clearly needed the money more than I did, so it is what it is.
I frequently loan my mom money, but luckily she's extremely good about returning it.
And no worries. Stuff like this happens. It's funny, I'm extremely frugal and have the hardest time spending money on myself, but if I lose it in some unfortunate way, it doesn't bother me that much.
