I just had a weird thought. In my country there's a law (I think some similar exists in most countries) that any organization, society, entity can only keep record of private nature about a person / entity if he/she/it gives its explicit consent to do so, and that consent can be revoked at any time by the person. So whenever I participate in a product related raffle for example, there is always a legalese text asking whether I give my consent that the data given by me to be stored by the company and used for further promotional offers - agreeing is not necessary for the participation in the raffle. (Here is an interresting point about how far WTS follows the law, we were taught how to code and keep records about people in field ministry, so that it can't be challenged before the law).
So to abide by this law every baptised JW has to sign a similar paper, allowing the WTS to store information about them. Now, according to law I can ask them at any time to stop keeping the record and destroy any available records. Of course, as pointed out above, they will simply find some loophole... However this should not be a DF offense (I don't remember the Bible saying that not giving your personal info to anyone is a sin), yet I wonder how would the elders react
Edit: On second thought I think the respons would simply be that I am breaking the legal bond between myself and the organization, and like with divorce, that breaking means I have just DAd myself. Oh wel... for a second I thought I had an idea to stir up trouble...
