服务器里很多这个名字，服务器打过补丁，但是这么多这个名字的人进来，本来服务器人数就不是太多，现在好，都是这个，其他人都进不来了~~
无语了！！！ 你的补丁应该没有打正确吧 补丁打过了，要不服务器早挂了，现在问题是服务器没挂，只是很多 Born to be pig 的名字的人连接 这样，吧服务器的位置全部占了，别人进不来~！ 我也遇到这样的问题:被炸,装了补丁后好点,比赛F也被炸,不过有密码没炸成,就是里面的人ping都230↑不知道谁无聊玩炸服 Born to be pig ( timed out

遇到这个情况，可以查看，hlds的窗口或日志可以看到攻击你的名字后面的相对应的ip，封了他就不完了 本帖最后由 野*人 于 2009-2-5 05:01 编辑
人是人他妈生的，所以有人性。
妖是妖他妈生的，所以没人性。
而没人性的，我们可以简称为--->>畜生！
随便说的，捞分，走人.... 查询攻击来源,然后....反攻~!;P
