dkbit98 tried that for us, I tried them later after his findings and I can confirm that it is inaccessible and was probably --as dkbit98 suggested-- put there only to confuse visitors and ultimately led them to use the fake clearnet.
Yes I did try it, and my conclusion could be wrong only in case if that onion address worked in past, or could possibly work in future, but it's highly unlikely.
I know how most scammers mind works and I think it's just bs address with few letter swap.
Like some people suggested before me, best protection against attacks like this is to bookmark Sinbad page, and all other pages you are using.
In last few years I realized most of the people don't use their brain at all, so it's possible for them to get scammed with this cheap tricks.
