[SEC/FIX]LeaverBuster v0.4 - Deal with leave and kick-spammers [1.0.1-R1]

LeaverBuster
<Edit by Moderator: Redacted bit url>


This will ban players who are leaving too many times within a set time period. This will deal with those who spam leaves, which seems to have become common practice these days, unfortunately. As of v0.3, it also tempts to counter fake-kick packages spam.
This is especially useful for non-whitelisted servers.

Video demonstration, voiced by a good (Russian-American) friend of mine, @EnigmaBADGER.

I have written this from scratch, although it seems to have the same functionalities as SpamBuster (being up-to-date however).

Functionalities:
* It will ban players who have been leaving too many times (customizable) within a certain period (customizable).
* It will ban players who get kicked more than X amount within the given timeset. (A new exploit.)

* You can choose whether or not to have the player joining the game, reset the "leave" timer.
example:
Player Abc has joined the server.
Player Abc has left the server.
Player Abc has joined the server.
Player Abc has left the server.
Abc will not get this player banned with this setting enabled.
* It will log when a player is banned for leaving too many times within the specified time.

------------------

Please read this short information box on leaveScripters below.

How does it help my plugin?
Plugin-wise, in absolutely no way.

Then why on Earth would I donate?
Time and effort was put into this plugin. Maybe this plugin makes your life easier, gets your server more players or simply makes you and the players have a good time.

How do I donate?
You can donate through PayPal. If you do not have the means to do so, you can also "donate" by showing your appreciation in the form of a nice comment. These donations and comments keep me motivated. Oh, and it keeps me alive in this overpriced studentroom I live in. It means the world to me.

Thank you for reading this.

Thank you kindly! The prefixes have been added.

 

FANTASTIC!

 

Added BukkitDev link.

 

Approved

 

Good idea, but what If someone is having connections difficulties and keeps leaving and timing out straight away? Does it only work if they join and leave instantly repeatively, or does it count how many leaves they have done and ban them after they have left too much?

 

This depends on one of the settings, ResetOnJoin, which defaults to true.
You can find this setting in the config.yml file in plugins/LeaverBuster.

Example:
Player Abc has joined the server.
Player Abc has left the server.
Player Abc has joined the server.
Player Abc has left the server.
Player Abc has joined the server.
Player Abc has left the server.
Player Abc has joined the server.
Player Abc has left the server.
With this setting enabled (true), player Abc will not get banned.
With this setting on false, player Abc will get banned.

I suggest one leaves this setting 'true'. As players who time out straight away due to connection issues will not get banned due to leaving too much within a timespan.

I hope this cleared things up.

 

I have a question:

How does one "spam leave" if not by repeatedly joining and leaving the server? Am I missing something, because I don't understand the point of the ResetOnJoin setting if it allows the spamming to continue?

 

People are using scripts and hacked clients to spam 'fake' leave packets.
They stay in the server whilst leaving a million times.

 

This = Awesome.

 

Ah thanks for the clarification, everything makes sense now!

 

Why do they spam Leave packets? What does it accomplish for them?

 

Well, it lags any server and it'll make it crash in the end if there is no plugin like this one installed. The question is similar to "why do people grief?".

 

lol thanks. I did meen literally what does it do to the server, not why do they do it.

 

I'll suggest everyone taking part in this argument take a deep breath and calm down. Having reviewed the source of both plugins I am sufficiently convinced this is not a copy.

@Mrchasez
Publicly posting in a thread suggesting a plugin is a copy of another is not the proper way to handle such a situation. If it is your plugin, you should contact a moderator privately to handle the situation, if it is another user's plugin, you should report the post of the suspect plugin and/or also contact a moderator.

@Rahazan
While as a plugin developer I can understand the need to publicly defend one's work, I would appreciate it should this happen again you report the post and/or contact a moderator.

@tommygoesha
If you see these sorts of arguments happening, even if you know some of the parties involved, you should report the post and/or contact a moderator about the issue.


We take plugin/code theft seriously, and publicly arguing over it isn't the way to handle it. I hope that in the future you will all take more prudent steps to handle such issues.

 

@NuclearW
Ok ^-^

I was just checking.

 

*nods* agreed Thank you

 

@NuclearW

Could you remove everything that has to do with the flamewar, including this post, as it has been settled now?

 

I wanted to give you all enough time to come back and review.

Now that you have I've deleted the posts.

 

Its not working on my server.
It dont stop them at all.

 

Very handy plugin, almost essential if you don't want to get attacked by skiddies.

But it's not working on latest bukkit builds, please update

Thanks in advance.

 

Yeah it really hasnt ever worked

 

Could you just stop trolling in this thread? Thank you.

I will update it once I have access to the sourcecode, it is stored on my desktop computer at my room where I am not at right now.

 

Woah im not :<

I really wish it did.
Those damn spammers ಥ_ಥ

 

Updated for CB#1542, it should work for all of the latest CraftBukkit builds.
If you wish to have the new fine-tuned values in your config.yml, please remove your config.yml and it will replace it with the new one.

 

thanks
Hopeful this one works

 

It has, unfortunately, been confirmed that this doesn't work for all hacked client leave-spams, I will investigate and try to edit where needed.

 

Does it stop the common ones (ノಠ益ಠ)ノ彡┻━┻
I need the spammers to stop! ㅠ.ㅠ

 

Oke thanks,
Also try to add a function for the kick spam.
There is a new client where players use something where they get kicked.
then it keeps spamming ..kicked ... kicked ...kicked ...kicked
Antispam and you plugin dont stop this kind of attack.
I have no link from the client cuz i have no idea what it exact is.
But i hope you wanna look into this after you got the main one working.
