- Google translate can help, sure and I see this tool is improved a lot than 2 or 3 years ago. Nowadays, it translates smoothly and in some context, some phrase, the translation is good enough to understand.
- Fundamentally, posts if are released in very short can bring troubles to posters (burst-posting). Except it is for topic creators.
- Quality of the post: if the quality is zero or very low, there is unnecessary to spread it around multiple boards. Such efforts are considered as spamming or shilling projects.
- Intention when translate original posts to local languages. You can link it with PMs. If PMs are used to advertise your services or unsolicited PMs, the sender can get troubles (temp ban) if receivers report it to moderators. Even the ban is applied, the ban-time will be different (the more PMs or the intensity -- same PMs within shorter period, can cause longer ban-time)
There are multiple things will be considered by moderators.

Sorry BitcoinFX, you are banned from posting or sending personal messages29. Sending unsolicited PMs, including but not limited to advertising and flood, is not allowed.
You sent over 100 PMs with the same format: clear unsolicited bulk PMs. 4 people reported it, making it unwanted & unsolicited bulk PMs = spam. Most others would've been banned much longer.
