Any time you have to fill out and sign ANY government form for ANYTHING, you are “in their records” and will remain there in perpetuity to be used in ANY WAY the government sees fit.
To believe otherwise is willfull stupidity.
That's for sure and here is the proof. We've all heard the stories of someone who was listed as dead by the government when they are very much alive. Even with the help of their congresscritter it is nearly impossible to get them to un-dead you in the records.
Personally, if the gov decided I didn't officially exist anymore I wouldn't argue it.
