I just deleted a spammer's comment in a topic, now the entire topic is gone!

[David N.]

This is normally routine procedure: I get an email of a new post requiring approval: 

Reese7713 has posted a post in a topic requiring approval, Midi Chase

I click the link and see the post. I realize it's a spam comment so I click the red "Delete" button which normally deletes only the post. I then go to my acp, search for the user and delete the user. Now the entire topic is gone!

I went to my moderator log to check and sure enough all I did was delete the post, not the entire topic: 

This literally just happened (10:22am). Here's the moderator log (the top line is the spammer, the two following lines are me).

When you deleted the user, if you have left the default option for what to do with that users content, it would delete it

I understand now: that entire topic had been started by that same poster I deleted, only it looked legit so I had approved it a couple of months ago, and today he replied with a spammy comment. 

All is well. I got scared for a second. 😰

Thank you Marc!

No problem at all 🙂
