Adam Buckley's Use of Emoticons

Buckley rarely uses emodicons. However, when he does, he only uses the :-) emodicon. He hasn't been seen using any other ones. However, on Wordpress, it automaticly converts the :-) emodicon to the smile emoji. On Scumbags of the Internet #8, he incorrectly states that he used an emodicon, even though you clearly see he used the smile emoji.
