Exclamation A dude crashing samp servers

Hey all.
I don't know if you heard around, but it looks like there's a 'new' hack for sa-mp to crash servers and it actually works.
It happened to me today, there's a cunt who has nothing better to do but join random servers and crash them.
I get no errors and I have no clue how to avoid that. But if any of you know anyway to fix it please help me out.


Bare with me, and read.

So this dude recently joined my server and he started using invalid characters text, on player text. Okay so I did a quick script to fix that, and it worked, he couldn't crash the server anymore using invalid characters.
Yet after that, the dude seemed he found another way by teleporting or attempting to delete objects from the server.
I have no clue what he actually uses but all I get is some teleport warning since I have anti teleport in my server.

Code:

I actually have no clue what's causing the server to crash and I don't know a way to debug those stack code.
If anybody can help me out please do so, you'll be kindly appreciated!

You're using the SKY plugin that has a known server crash exploit, you need to update it.

Thank you for replying! Appreciate it.
I've updated it and looking forward to see what's going to happen whenever the 'crasher' will try again to crash the server.
Once again, thanks!

EDIT: Works perfectly fine now. He attempted twice but failed. Thanks a lot dude!
