P.S. I do not want to be cynical. I understand that this will be a very hard time for people living in Russia -- just at the moment it seems much worse for people living in Ukraine, and there seem to be few non-violent options to stop this apart from sanctions. Meduzza looks like a legitimate site and I have donated EUR 100 to them on your behalf.
P.P.S: Please note that the payment setting on the site defaults to monthly.
