Ok, I've read through Do posts have to be in English on Stack Exchange? and How should we handle non-English answers?. They encourage new posts in just English, but I didn't see a decision about how to handle existing content in other languages.
On one of the Beta SEs, we have a member who semi-regularly posts comments in what I assume to be a dialect from India. For example, his most recent comment reads as follows:
gupta ji apne last question pe bhi najar daalo..
Should non-English comments...
- be flagged
not constructive / off topic? - be flagged
other(with a comment)? - be left as-is?
- be dealt with some other way?
I understand the official policy is to post questions in Englishthe official policy is to post questions in English. What should be done with existing comments that are in other languages?
