If your question and answer history doesn't go back very far, then it probably wouldn't be that difficult to keep a record of the questions that you've asked and answered, but if your question and answer history goes back years, or if it's extensive enough that it encompasses hundreds or thousands or even tens of thousands of items, then it would likely be a lot more trouble than it would be worth to record all of them. Look at it this way, there's no statute of limitations on what can and cannot be reported, flagged, or removed. Once you post something to any of the forums on this site, it becomes the property of Yahoo!, and even if your account is suspended later, the content you've uploaded will remain (so long as it has not been reported and taken down.) And furthermore, if this site ever closed down, Yahoo! would be free to do as they like with whatever content exists here, so if they decided to call it a day tomorrow, all of those links would be dead anyway. What's the point? If you think it might be a good idea to record your activity because your questions and answers keep disappearing, then you might look into refraining from posting content that people feel violates the community guidelines that we all agreed upon when we signed up.
