Gotta start re-formatting your hard drive(s) before the FBI comes to your house with a search warrant lol. They are coming for your porn, bro.
Of course, it is only worthwhile re-formatting an encrypted hard drive. If you re-format an un-encrypted hard-drive, then the evidence isn't fully erased; it can still be recovered with digital forsenics software. To fully erase evidence, reformat an encrypted hard drive, and re-install an OS over the re-formatted HDD.
btw I just re-formatted my hard-drives to be safe, don't want anything weird on it.
That's my advice. Hopefully, this was helpful information.
