Last part confirmed to be true. Welcome to Trollnogi.

As for the page itself:

• New description: This bomb will give another player a timed quiz! Use it on a player you suspect of botting. But beware, using these on nice people could make you a few new enemies. Try saying hello before you blast them back to the stone age!
• Bombs can be used on players who are gathering.
• Lock duration lasts between 30 minutes to 24 hours.
• Lock duration is displayed in minutes.
• Lock duration appears to be based on:
  • How long the character was logged in (needs more verification, since the other seems more plausible).
  • How many times the account was bot bombed (successfully?).
  • Formula has yet to be determined.
• Lock duration only goes down if the player is logged in.
• Locked players can be targeted (unlike what it currently says), but cannot be attacked.
• The captcha prompt is always two words, the first letter of both words is always capitalized.
• The captcha prompt can be refreshed for a new one.
• Also according to the thread:
  • Captcha prompt duration lasts 2 minutes.
  • Refresh can only be performed twice.
  • A player cannot bot bomb the same person more than twice per real-life day. Dunno what reset time is (12am or 7am PST).

Changed "How many times the account was bot bombed (successfully?)." to IP address.
