# File: MessageHistory_SQLite.pm # # Purpose: SQLite backend for storing/retreiving a user's message history. # Peforms intelligent hostmask and nickserv heuristics to link nicknames # in order to ensure message history is stored in the right user account # ids. This is also extremely useful for detecting ban-evasions and listing # also-known-as data for a nickname (see the !aka bot command). # This Source Code Form is subject to the terms of the Mozilla Public # License, v. 2.0.
