1. why are you asking that question on this forum?
2. what would make you think that "random strangers" would paypal you donations?
3. I would assume that it's perfectly legal to make a website asking for donations as long as you're truthful about why you're requesting donations. but nobody is going to donate money to help you buy a new car you because you "fell asleep", totalled your car, and didn't have collision insurance.
3. since you are not a legitimate charity; I don't think donors can legally write off any donation to you.
