Yes, of course "Adam S." (not actual name) just links chip selections to earn some cash.
But I've assumed that someone with real flesh & blood fingers is typing the messages we see here.

In fact, among all the common chips on eBay, he generally picks some interesting, older material that a seasoned collector might be interested in. While it may not be museum-quality curated selections, I will often take a look, and on rare occasions, bid on something he's promoting thru his bot.

Here's a screenshot of the past 30 or so Adam S. postings. Certainly more interesting that 30 random eBay chip listings. That's why I expected him NOT to promote that mule in today's listing. JMHO
