Acamar, auto-learning spam blocker.

Acamar learns player's chatting behavior and identify bots and spammers out from normal users. You don't need to configure keywords, just simply select the level of filtering and the addon will begin to learn, and as more information is learned, the filtering will become more accurate.

In most cases, 90 minutes after running, 90% spammer should be identified and could be blocked, and >95% spammer should be identified after running for 1 day. Spammers may change their ways to bypass the filering, but hit rate will remain high unless spammers' behavior act like normal users and thus makes they become not so annoying.

Highly talkative users may be identified as spammers, but they will be removed from blocklist after certain period of being less talkative, or filtering level could be set to less strict level to avoid blocking of these users.

Acamar introduces the concept of dynamic blocklist: Once identified as spammer, the player will be banned for hours or days or years, depends on how heavy the player spammed, and will gradually return to normal once stop spamming.

No configuration needed.

Filtering applies to following messages:

1. Channel chat (Guild, team and Raid messages were ignored,)
2. Say
3. Yell
4. Custom emote
5. Whisper

Settings

1. Filtering level: Players with pam score greater than the level will be blocked
2. Filered channels: Select which channels the filtering will applied to
3. Do Not Disturb: Quiter mode
4. Rewrite messages: Messages with repeated substring will be rewritten to shorter form
5. Do not filter friends: Players belongs to same guild/party/raid or myself will not be filtered
6. Minimap icon
7. Limit max frequency of same player or same content

Unlimited blocklist and whitelist

Supports unlimited blacklist and whitelist.

Adding or deleting of players from ignore list will synced to blocklist, and you can also SHIFT-RIGHTCLICK the player name in chat window to bring a popup menu to add the player to blocklist or whitelist.

API

For addon developer: If you intent to use Acamar Spam Engine as your message filter, API code sample:

    local acamar_api = _G["AcamarAPIHelper"]
    if acamar_api ~= nil then
        -- blocked: If the player with guid should be blocked.
        -- spamscore: The spam score of the player. The greater, the player's 
        -- behavior is more like a bot. Normally you don't need to use score unless 
        -- you want to classified spam players into more specific groups. 1 is good
        -- in most circumstances.
        local blocked, spamscore = acamar_api:IsBlock(guid)
        if blocked then
            -- add your code if player should be blocked
        end
    end

Acamar support both retail and classic of WoW. But not fully tested on retail version.

Acamar-自动学习垃圾消息屏蔽，支持魔兽世界怀旧版。

Acamar学习用户的聊天行为，从中辨识出正常玩家、垃圾发送者以及脚本。只需选择过滤的级别，插件就会自动学习，随着学习的信息越来越多，过滤就会变得越来越准确。

一般情况下，安装运行90分钟后，约90%的垃圾发送者和脚本将被识别出来并且可被屏蔽，一天后，垃圾信息玩家识别率可达95%以上。垃圾发送者可能会想办法绕过过滤，但是过滤效率将会保持在高水平上。除非这些垃圾发送者的行为越来越像正常玩家，当然这也让这些人的行为不那么烦人。

过于健谈的玩家可能会在一段时间内被识别为垃圾发送者，但随着他们变得不那么健谈，一段时间后他们会被识别为正常玩家。当然也可以通过调低过滤的严格级别来避免误伤。

Acamar引入一种概念叫动态黑名单，即：垃圾消息产生者根据行为轻重，会被禁止几小时、几天、甚至几年。当不在发垃圾消息后，会逐渐降低垃圾得分，直至移出黑名单。

无需配置。

过滤对下列消息有效：

1. 频道聊天，包括世界频道 (公会、组队、RAiD频道消息不会被过滤)
2. 说话
3. 大喊
4. 自定义表情
5. 私语

设置

1. 过滤级别：垃圾评分大于设定级别的用户将被屏蔽
2. 过滤频道：可以选择哪些频道进行过滤
3. 尽量勿扰：除非必要，否则将运行在更安静的模式
4. 精简消息：重复啰嗦的消息会被简化
5. 不过滤好友：自己、好友、团队以及小队里的成员可以排除过滤
6. 支持小图标的显示及隐藏
7. 同一用户以及同一内容的消息可以被限制发送的最大频度

无限黑名单和白名单

突破系统限制，支持无限黑名单和白名单

在游戏中添加、删除屏蔽用户时，这些操作会同步到Acamar的屏蔽名单中。也可以通过按住SHIFT，然后右键点击聊天窗口的用户名打开一个菜单，将用户添加到屏蔽名单或者白名单中。

API

插件开发者可以通过下面的代码来使用Acamar API在自己开发的插件中过滤用户：

    local acamar_api = _G["AcamarAPIHelper"]
    if acamar_api ~= nil then
        -- blocked: 用户guid是否被过滤掉
        -- spamscore: 得分。用户行为越像垃圾信息发送者或脚本，得分越高。多数情况下，
        -- 得分无需用到。如果要用，1 在多数情况下用来区隔正常用户和垃圾用户比较合适。
        local blocked, spamscore = acamar_api:IsBlock(guid)
        if blocked then
            -- 当用户被过滤掉的代码
        end
    end

Acamar 支持怀旧服和正式服。不过正式服上没有经过完全测试。
