I don't think you can prevent it. As a matter of fact, i've just confirmed by myself that i'm right about Barrow Hill by googling (i knew what horror game is zobraks' favourite
) so it really comes down to whether someone really finds amusing to guess by searching on Google for it. I admit i would sometimes go to some list of adventure titles if for instance, i suspect it's a horror or comedy game to remind myself, but to look for the exact answer would kill all the fun for me.
