This could be a tracking link to help them know how many visitors came from this topic. I don't see why an official representative would post a referral link.
though you are not asking for KYC till it reached 2k euro yet there is a need for assurance for this part because sometimes even if this being said the site will accuse players of cheating so they will have the rights to ask for kyc.
