yeh it's a pain but turning off your comments is not the answer.
If there's one dead horse that's not worth trotting out when it comes to Social Media, it is the one about "comments." Should you have comments on a Blog? The staple answer is, "yes. Always." But that tide may soon be turning...
My Answer below;
Feel free to delete comments from your blog as "obviously you are the smartest person in the world and have nothing to learn from anyone else in the world".
While you are at it - why not surgically remove your ears and ear drums (mmmm nice and quiet), that way your mouth will still be able to talk.... but you wont be forced to listen.
