I guess for a non-english speaker taking someone else's long comment and going in there with a fine tooth comb to change specific words here and there is easier than trying to write out something in english - or using google translate... I guess....
Except, I feel like it isn't. It seems like more work than just typing something into google translate that's super generic and getting a poorly translated but different response.
That would definitely be more effective than the former approach, which seems to misapprehend the nature of language itself insofar as it results in the most overtly suspicious comment possible.
