I also use shodan.io to find and leave random messages on private minecraft servers which I sign with random names (once the message was "Have you heard the good news of our lord and savior Kelsier the Survivor?") and my friends/enemies' phone numbers (friends with consent, enemies without). (If this happened to you it may have been me).
TPBM has had their minecraft base griefed/vandalized in some way
