What a great response! Even if you hadn’t flagged him, you could’ve ignored him. But by taking time to comment, you’re helping him improve himself. You’re also setting an example for others who see this.
Having lived in many cultures, what’s appropriate in one setting is completely inappropriate in another. Sometimes (not all the time) I think this is a problem on Steemit. Most of the users are Western, so it can be difficult for other cultures to understand the etiquette especially in an online setting.
Thanks for setting a great example!
