The forum rules are very clear on that. Making posts using google translate or anything similar is forbidden.
Mind to qoute the rule that states so?
You had better add the previous sentence to the quote to understand the context:
You can’t use a translator and post in other local boards where you don’t know their language as well.
So the rule he is referring to is rule number 27.
27. Using automated translation tools to post translated content in Local boards is not allowed.
That said, mindrust is wrong:
If everybody was using a translator to make posts, all the posts would look the same.
For many years, non-native English speakers have been using these tools in the forum, which has allowed for a better written English. And no, as everyone can see not all posts look the same because online translators have improved so much that they are able to translate the nuances and style of native languages into English.
