I just came across this thread and wanted to repost the images in order for them to display in the thread without using external links.
Reading the replies from the DuckDice.io account is contradicting what was written by DuckDice in the chat. Here they say "if" but in the chat they are effectively accusing him. I have to say, there is no chance the OP is the only who uses/used Tor to access their website for anonymity therefore this probably cannot be the only case where they made accusations.
Their level of professionalism towards customers in this case is basically at the lower end of the spectrum. Making huge accusation and stating it is a matter of fact is not acceptable.
