@JimmyB @aral Per Muslim Legal Fund of America:
"Providing aid through unlicensed U.S. charities or foreign charities is not advised because their aid may be considered material support of a foreign terrorist organization.....Providing direct aid to individuals or relatives in Gaza is not per se prohibited; however, it is not without risk. First, providing aid to any person in Gaza who is a member of Hamas or conducting combatant activities under the direction and control of Hamas can be considered material support."

I imagine for-profit companies such as GFM would be highly suspect of potentially providing material aid to terrorist groups, or individuals in locations controlled by said groups.
Hamas is designated a terrorist organization by the European Union. If I recall, Gaza Verified specifically does not vet individuals for Hamas affiliation.
That doesn't mean all individuals in Gaza are affiliated with Hamas. But going outside of official channels distinctly raises risks.
