This is why on the rare occasions I feel like sending monetary support in any potentially volatile case, I don't use GoFundMe, or PayPal, or send a check. I stuff a $10 or $20 bill in an envelope, put a stamp on it, and mail it from a post office box in a town other than my home town.
It sucks that we have to think that way but, as the saying goes, "Just because I'm paranoid doesn't mean they're not out to get me."
