Claim Intrusion Alert: Open Parties and Claims & FTB Chunks
by KURONAMI
Claim Intrusion Alert tells a territory owner when someone tries to grief a claim or chunk, reporting each attempt in chat.
What it does
When a player breaks, places, or interacts with a block inside a claimed area, or uses an item or interacts with an entity there, the owner receives a one-line chat message naming what was tried and where. Attempts blocked by another mod before this one sees them are still reported. Teammates and allies never trigger an alert. Repeated attempts by one intruder against one chunk are grouped so a persistent griefer cannot flood chat.
The mod works with FTB Chunks, Open Parties and Claims, or both together, and either one is enough. Neither claim mod tells the owner anything about blocked actions on its own. Attempts made while the owner is offline are stored and posted the next time the owner logs in, with a limited number kept for a limited time. It is server-side only, so clients need nothing and players see no extra screen or overlay. Messages are localized into 9 languages.

What the author says
When someone tries to break, place, or interact inside your claim and the claim mod blocks them, you get a one-line chat message saying who it was, what they tried, and where. Works with FTB Chunks and Open Parties and Claims. Either one is enough, both together is fine, and neither of them tells the claim owner…
