When someone posts their FIRST post, their profile tends to say they haven't posted anything yet. Answered

 I have been noticing this for a number of days, but thought it was just me....I see someone post in the Forum list, someone I haven't seen before, so I go to their profile and it tells me they have not posted anything yet.  

Let me see if I can find an example....

Here's one: 

Maxim2735 has not posted any comments yet...

  And yet:   https://www.instructables.com/community/What-can-I-do-with-lots-of-Magic-The-Gathering-ca/

Is this because he posted on his own Topic and it doesn't count then?
