There have lately started appearing comments on posts such as:
Please clarify your specific problem or provide additional details to highlight exactly what you need. As it's currently written, it's hard to tell exactly what you're asking. – Community Bot
I am curious about how these are generated and who is behind them.
I remark that I have seen posters being unsure whether this "bot" should be taken seriously, and also, because of the very general wording, unsure of what needs to be fixed in the post.
Are these "bot" comments really useful?
