[NEW] For Brouhahaha GLITCH

This "trade glitch" manipulates Roblox's currency system to seem like you sent a legit trade, but you never did.
For this method to work, you will need a semi-large limited, (like a Classic ROBLOX Fedora with some robux), to make your victim want to accept the trade.

Another thing you need is some sort of currency of robux (R$). You could find a cheap t-shirt, like for example, there are some for 2 robux. So here's the crucial part of the glitch because you need to do it really quick. Don't buy the shirt/t-shirt yet, as we will get to that later in this guide.

Type 1:
The first thing you want to do is to find a victim, and once you've found him/her, tell them for example that you have the Classic ROBLOX Fedora (you have to have the item itself) and let's say that your victim has a Valkyrie Helm. (Big price difference)
So what you do is that you send a trade to your victim and include his Valkyrie Helm, Your Classic ROBLOX Fedora and all of your Robux. As soon as you have sent the trade, switch tab to where the shirt/t-shirt you were going to buy and basically click buy (the shirt/t-shirt). Now you won't have enough robux to complete the trade as you just used some, so ROBLOX will send you a mesaage like this: "Your trade was not able to be completed. This can happen if one of the items is no longer tradeable. You may want to try sending your request again. Go to the trades tab to review your trades".
Now here comes the glitch part, your victim (that you sent the trade to) can still accept the trade and it will appear for them as they just got a CF for a Valkyrie and also 'profited' by that, but they HAVEN'T, because, the trade can not go through.
You then send another trade with your smallest limited that isn't worth much for their Valkyrie Helm. And so like, they will most likely be like: "Oh I just took this dude's CF, I have to give him my Valkyrie because he will report me for scamming..". And if they try to "run off" thinking that they actually got the CF, well they can't, because it's basically a glitch and because the trade couldn't even go through, it's also known as, 'Couldn't be completed'. If they do accept for your second trade with the small limited for their Valkyrie Helm, then they just got lured by you.
To make this even more legit, you can open a chat with them and tell your victim to turn their trade filter off because some people have their trade filters on High, so when you send the trade for the Valkyrie Helm with your small limited, it might not go thru. If you have a chat open with your victim, you can actually convince them to turn it off.

Type 2:

Type 2 of this method gives you a better excuse for the person to turn off their trade filter so that you can send a small limited for their big one, for example the Valkyrie Helm. So instead of sending one CF, send two for their Valkyrie Helm. When you've sent the trade, tell the person kindly in the chat that you accidently put two CF's in the trade and ask them to counter the trade and put something else in there. You can lure them by saying something like, "Give me your teo beast mode faces and you can have the second CF", and that is a big price difference and your victim will think that it is pure gold for them. And then repeat the glitch.
This obviously works better if you have bigger items such as some dominus, etc, because the trades look more legit and it's easier to fall for it.

Yoy can also try to do this on your alternate account (if you have one) that might have a small limited and all of your robux by doing the same method. You basically buy the shirt/t-shirt etc, etc and log into your alternate account and do the same type of process.
