I have been online since 1993 and had been taught and continue to treat everything I post as if it will never be deleted. I don't see a point in deleting my accounts when the data has very likely been duplicated the instant I sent it and could still easily be reposted or used by whoever has access to the database it is stored on; let alone the multitude of unknown bots and agents that may have duplicated it independently.

So, no. It never even crosses my mind because I think it is rather pointless. Of course, it is also because I don't really talk about my personal life in detail enough, or use my real name online so my online identity can be linked to my real one and don't have any fear of something I said when I was 9 being used against me now that I am 41.
