As with any higher-risk higher-reward investment, there are almost certainly people who dove into it far too enthusiastically and lost more than they could afford to lose.

Most such reports probably won't end up in the comments here.

Technically, I believe one is only supposed to invest up to 10% of their net worth in Lending Club, and must meet some other financial suitability standards: https://www.lendingclub.com/info/state-financial-suitability....

Of course, as far as I can see this is just a checkbox saying "I agree and meet these standards." No way for them to verify.
