Guys do not tell me please how can I find a user on the forum? We have one claim but we can't handle it because the user didn't provide their username. And the nickname under which he introduced himself on btcgosu is not registered on Neodice (there is also no request to withdraw the amount that the user specified). Perhaps someone knows a user on the forum under the nickname "Kevo65". Thank you.

Using Ninjastic tool and the username you provided I found a forum user with a similar name:
https://ninjastic.space/user/Kevo65His profile in the forum is this one:
https://bitcointalk.org/index.php?action=profile;u=3539918I believe there is a good chance he is the same person, since it seems he has already talked in this thread and expressed he had some problem this Neodice, according to this message I found on this profile.
So, if you feel like checking this out and ask him for proof of onwership of the account, it may be worth it to try.

These guys have not answered me about my withdrawal for days and now are hitting me up for kyc to withdraw, not so sure I should submit my private info to this site as it doesn't seem too reputable from my research, any suggestions?
