So just how long is it going to be before a thief makes a donation to some charity which the victim dislikes (e.g., an anti-abortion victim whose card is used for a pro-choice lobbying site), and the victim sues the recipient of the donation, or accuses them of being the thief? And of course, there is the possibility of someone stealing a card in order to make the donations. Various oddball political and religious groups have been accused of such, and in at least one political campaign the charges were proven, and the perps went to jail.
