I lean towards calling this one bullshit. If the report came out AFTER the supposed event, hmm maybe, a huge maybe. But the news report come out BEFORE? No way.
Prostitution is illegal in Taiwan, of course it doesn't mean it doesn't happen. But it's hard to locate and buy commercial sex in Taiwan without a local guide in last few years (do you want to guess how I know this?) Well actually it's always been illegal, but the authority had been lax about enforcement for decades, that changed about 10 years ago.
I can assume AV idols making "private arrangements" in Taiwan (I think slightly less so in China, but that's a whole different ball) is a regular happening, but it's all private arrangement. Meaning you and I can't walk in a place with a pocket full of cash and expect to get an AV experience.
If the report really come out on TW newspaper, you know the police will have to show up, the authority can tolerate private arrangements, but making the newspaper and especially if reporters manage to snap a photo or two and the police failed to arrest someone for it, there'd be hell, especially from the very noisy Christian lobby. Japanese tabloid (linked by TP) of course seize on one or two online mad fans, I'd bet a dollar those are posted by cherry boys who can't even afford or get access to regular hookers.
