@Titanwarscammer if you forgot your login to your Discord then you can't, why did you make a separate Discord to contact him?
1.) You didn't request a Sythe PM
2.) You didn't take any in-game screenshots of trading the gold, so there's no proof you trading him anything
3.) You've lost your Discord login information and proof from Discord
While I don't doubt you were scammed, I hope if nothing else this is a wake up call for you to be more vigilant in any future trades on Sythe. Also, your Discord is Peteri#7880 not peteri#7880 - Discord names are case sensitive (this is another common scam).
Sorry for your loss. I'd highly recommend you read the following guides to stay safe while trading on sythe:
1.)
ALWAYS request a sythe PM, make sure the PM includes both your Discord Name and UIDs as shown here:
Discord PM Template. Example of a correct PM:

2.) Familiarise yourself with who you can trust:
Trading 101 - Vouches, donor status and how you can stay safe!
3.) Learn how to stay safe from Discord scams:
[Important] Confirm who you are speaking with on Discord!
4.) If you're still unsure how trustworthy someone is, use a middleman from here:

@Titan War while proof might be lacking here, there's no doubt that you're a ban evader:
