One of mine did MLM for some weight loss product. I figured out soon after she arrived that she was not very smart-- but wow, signing up to sell scammy MLM products is really dumb.

Toro Toro was the club my au pair was working at. The owner clearly liked to hire au pairs and there was a whole group of them. I'm hoping being a shot girl was all she was paid for. It seemed incredibly shady to me.

Babysitting
Housesitting
Pet sitting
Dog walking
Deliveries
Driving Uber/Lyft
Promoting things on YouTube and other social media

Etc.

My former aunpair was also a dog walker. She went to the same house 5 miles away in our car everyday and I figured it add her boyfriend who worked from home, but nope! She later let slip that she dog walked.
