We found out that Mr.B met with a journalist to help him publish what he knew, we don't know when or where exactly, but our guess is they met in a hotel, see if Mr.B shared anything about this meeting in social media. All we know about him besides his alias is a strange name known to be used by him (THE4llANDP0werfu1MrB). Find the hotel's name and submit the flag like below: Hotel Name: Test Hotel, Flag: SBCTF{Test}
I searched THE4llANDP0werfu1MrB in google and found his instagram account with the photo of a hotel room. I downloaded the photo and searched it in google image search and I found the hotel name *Bellagio*
