reply via email link under each post
I came across this post https://destroytoday.com/blog/reply-link-in-rss-feed-posts where author added reply via email link under each post. I understand this is done by modifying the loop.
After further research on the topic I came across this article https://www.wpbeginner.com/beginners-guide/how-to-link-to-an-email-address-in-wordpress/ where they recommend against this option as it might cause a barrage of spam.
Question: it seems very convenient option if comments are off, however, can this really cause lots of spam email?
