The "(*ﾟｰﾟ )ゞ" emote is typically used to express a sense of embarrassment or shyness, often in response to a compliment or praise. It can also be interpreted as a bowing gesture. The "Yes sr blush" emote is less common and may refer to blushing in response to being addressed as "sr" (short for "sir"), possibly in a submissive or respectful context.
