Hello sir @altseller666 - You will need to collect this users Unique Discord ID and make a GIF of you copy+pasting it, follow this guide: Discord PM Template
For discord trades I'd highly advise using this PM template to avoid getting scammed.
My discord is: plankgang#5009 (SHOWN ON MY SIGNATURE)
Unique ID: 450645676158877726 (SHOWN ON MY SIGNATURE)
I provide Pm confirmations always. I've never Pm'd you to confirm my Identity.
I DO NOT BUY ACCOUNTS or RUNESCAPE PRIVATE SERVER RELATED STUFF - Imposter seems to offer these both.
This discord imposter has been around for months now. I'm sorry you fell for it.
Sorry for your loss.
EDIT:
I do not own discord NITRO.
What's discord NITRO?
Discord nitro allows anyone to change your last #4 digits of your discord ID. Thats how people can get the same discord id, but never your DISCORD UNIQUE ID
Feel free to open up a new report once you have provided the confirmation PM + unique ID of the user.
@Plank Gang doesn't have Discord nitro which can be seen by joining the Official Sythe Discord and simply @'ing him. Follow the template I provided above to have safe trading on Discord.
