Excellent question….
My thoughts:
When it’s been relevant and truly genuine —I’ve read and reciprocated.
When they throw it randomly with a please read—
I don’t clap it and typically say: thanks for reading—bc the truth is, I don’t know if they actually read (comment sounds so generic and their fishing for help without doing the real work so many of us do)
So bottom line: I’m with you!
If it’s genuine, why not?
And when it’s spamming—I’ve reported!

Have a great day!!
