The English language used doesn't look very trustworthy...

Unfortunately, not all people on this forum English is a native language. And the local sections of the forum are losing on the information content and relevance of information and communication. Therefore, many non-English speaking people are here. I see nothing wrong with that.
Throw you these racist talk. People communicate as they like. I think that for most users in this section of the forum, English is not native, but people learn to communicate.
