A user called scavin on crowdin add wrong translation to the discourse bot tutorial (here)
Which prevent every new user from finish the tutorial 
I already report it on crowdin. Is there anyway we can do to prevent this kind of thing happen again?
Also a question, do we have proofreading when someone update the translation?
Probably just a typo. It happens. And no, we can’t prevent that. We rely on the community to resolve such issues.
We have a proofreader for Simplified Chinese, but they look at those strings only twice a year. Thanks for fixing the translation meanwhile. It will be included in tomorrow’s translation update.
BTW: You might want to translate the word psst as well.
