Slight spoiler for Neal Stephenson's book "Fall (or: Dodge in Hell)".That idea is used early-ish in the book to muddy the waters and regain some privacy for a significant character. There’s a subplot involving a conspiracy theory being intentionally spread through online message boards and this character becomes a target of harassment. By flooding the sites with a full spectrum of scandals and red herrings, they’re able to drown out the pieces of legitimate personal info and confuse people enough that they move on to new topics.
