I don't see any problem with it as long as he can translate the announcement or white paper of the ICO project correctly or accurately.
Let's be realistic here. In order to translate something like that accurately, you need to have very good knowledge of the language. What is the likelihood that someone who is allegedly speaking Filipino, English and fluent Japan (and is wasting their time on random bounties)?
Because afaik, there are people who are bilinguist and polylinguist who can speak and write multiple languages precisely like a native writer or speaker.
Stating the obvious?
This is their advantage. But of course, if he is faking it and using, say, Google translator or any Japanese translating software/application, then it is not acceptable and should be reprimanded by moderators.
Just take a look at a single translation from them. It should be pretty clear.
