I think what the guy said is true, and he does provided a proof which seems to be true.
The proof by you visiting 1xbit.com.
Type 1xbit.com into your browser and click the enter button, you will notice that you will be automatically redirected to 1xbit1.com, this is something he clearly stated on the thread and I think that is a enough proof already, and the site looks like its been redesigned a bit as well.
What are you talking about? I visited 1xbit a couple of minutes earlier and didn't notice any changes to the site name or the site itself. 1xbit.com is what's displayed in my browser basically.
I did notice 1xbit1.com as the second result while searching for 1xbit in google results. This guy probably created a clone site in order to try and steal from the scammers which is truly crazy.
Both sites look like total scams to me which is why I advise avoiding them completely.
