See, people like to say that this is the case, but it really isn't.
Fukuda Kanon and Kanazawa Tomoko are but two examples of people who have mentioned other idols they're friends with.
Takeuchi has made reference to E-Girls, Miyabi has posted about her cousin in AKB.
Other have posted meeting other idols or showing of their CD's they've bought on their blog as well
If there ever even was a 'ban' on mentioning other idols, I'm pretty sure it's been gone a long time now.
