I found a pretty bad exploit that nobody's ever heard of, and I got attacked with it: Creating over 28000 Messages in a player will cause a Graphic Driver crash. It will reboot, and then you get the BSOD. It doesn't matter how powerful your machine is. I'm not posting the code for obvious reasons, test it at your own risk. Yes, I have reported this to ROBLOX. This is actually becoming "popular" as a trolling technique. I think ROBLOX should add a 100 Message limit? Discuss?

It's actually quite scary. Your screen will go into seizure mode. I've tested this on beastly machines with the same result. If you don't press ALT+F4 immediately, you're screwed.

Pretty much. I've been attacked twice by different people. It's super common in script builders, because some idiot placed it in an Admin Script. Let the abuse begin. My question is, who in the hell found this out by placing 28000 Message in themselves?

No BSOD. No big problems. Screen goes black for half a second. Message comes up 'Display drivers have stopped responding and recovered successfully." Does that a few times while I make my way to the minimize or show desktop button(s), I click, then close with Task Manager, and the problem is solved.
"It will reboot, and then you get the BSOD. It doesn't matter how powerful your machine is."

Those powerful machines, in my opinion, must have something wrong with them to have problems afterwards. I got little to not problems, like I said. And there's definitely machines more powerful than mine in every way.

Message comes up
Roblox window is lagged

Yeah, I guess I was exaggerating a little with the "no matter how powerful". My fault. Others have gotten the BSOD. But still, it's a pretty bad exploit.

Well if you REALLY want to crash, amp it up to 32000. That does it every time for me :3

I opened the dev monitors and it said

delta bw render: 1.88e+003

It's normally around 100.

I agree, we should use it for discipline while we can though.

I guess so. But it's different for everyone. Some crash, some can do it over and over again like it's nothing. That's the problem.

It's probably low powered/medium powered graphics cards that do that.
I'll try this when I get on my computer, my graphics card is boss, so is my PC, so I will see.

I still think a message limit would be beneficial, because who really needs more than 100 messages? O_O

Yeah. *guilty look*
Actually, I do my best to implement protection in SB. Sounds stupid, but it helps to break everyone's admin scripts :D

I'm pretty sure you'd have to be on a machine meant to run DOS

@Prehistoricman
Your Computer is God.

Anyways, I think we've established it's a rare event for it to crash. I still think that a message limit would be beneficial for abuse reasons. Other than that, I would consider this discussion done and done? Wouldn't you guys?
