It's 14 pages of comments and I don't think I can find the info you are talking about. What you say here is that someone else have the password, is that right? But even if he has the password he does not have the wallet.dat file so the password is useless.
There is no logic, someone to move the BCH but not the BTC, don't you think? The BTC cost apprx. 1.4M$ (even more on the time the bch was moved) compared to that the BCH are only 38k$ at today's rate.
If you have not moved the BCH, someone else have either the private key / the seed, the wallet.dat and your password.
Strange.
