It appears you promised to pay someone 1 LTC to create an account at a casino via your affiliate link, and did not pay when they did. Resolve that issue and you will resolve your trust issue.
OP should give that 1 ltc to the person whom op promised that OP will give 1 ltc. Though I do not think op will give that1 ltc. as 1 ltc is more valuable than the account of the op. At the same time OP should stop to send this type of unsolicited message as referral link does not allow by the forum.
My guess is the OP runs some kind of affiliate marketing business. It appears the OP "runs" the website martingalecalculator.com, which is the same as his forum handle, and any negative reputation on this forum would likely negatively affect the above website.
Also, although I don't know for sure, I think there is a high probability the OP has dome similar things in the past to get people to sign up via his affiliate link. I would find it strange if someone running an affiliate marketing business were to offer exactly one person money to sign up via his affiliate link and not pay.
