Btw, is there a possibility to see user's profile page based on their name, Like putting that in the url or something (i have tried, but it seems reaching to guess that url path). I know that we can see profiles by linking users in chat. This would create some transparency and credibility to check if these winner are real.

I understand if there's no such system in place, but i find that it would be easily done. As we can already visit on every profile in the chat if they are made public, so i don't see that this would be any different.
