By the way, I sometimes think that some of them are Ukrainians who are really asking for donations. Is there any directive out there for affected Ukrainian residents to get donations personally to the agency managing the official known donation address? Then we just need to refer the donor requester who come to this forum to that directive (including pretend scammers).
In fact, I already read in the forum about a crypto address where to send our donations, and it's a legit address.
I think it is better for us to donate directly to an official NGO or a reputable non-profit organization raising donations for Ukraine. We also need to be sure that every donation we send reaches those who need it. Those who need help should turn to these organizations and I am sure they will get all the help they need.
