Well, the short shrift is that the money passes directly to a couple of other organizations:
1.) First ActBlue
then, to:
2.) Thousand Currents (a la George Soros)
then to various overseas projects or BLM.
Only a small amount of donations make it to BLM Worldwide, where most of the money is eaten up by administrators, consultants, and travel expenses.
Only 6% of original donations trickles down to the local BLM Chapters.
During the recent period of most intense rioting, corporate tech giants and others were donating millions, even billions to BLM.
