I agree and think if you look at mkko88's history of posts I am sure that he was not specifically referring to Kyoto or GINZA at all. He was generally talking about the possibility of catching infections via BBBJ and has nothing to do with BBFS with which everyone knows is high risk.
There is a possibility that you can get infections via this BBBJ route not only Chlamydia but also other infections like non specific urethritis etc. The safest thing is CBJ as well as protected CFS.
Such speculation on a particular girl or shop has nothing to do with it. He was really recommendings CBJ, that is all.
