I really don't think you have to worry about that type of thing with GoDaddy (and I say that as someone who avoided them for a long time, because I didn't like their "in your face" advertising, but they have toned that down in recent years. Also, the founder killed an elephant in 2011.).
They have systems in place to prevent employees (at least low level ones) from looking at your account "just for fun". They basically need the 4-digit pin code in order to look at anything... I've needed help at times, but they needed that in order to do anything.
Plus, they have so many customers, and most of them are semi-clueless about domains (I recently saw a domain where the registrant picked businessnameinc.com even though businessname.com was available), so there's a very low "signal-to-noise" ratio... i.e. even if GoDaddy staff could watch, it would be
worse than looking for a needle in a haystack.
What I think probably happened was:
- There was a sale on .systems domains (I've noticed they have different sales all the time, and it can be on one day, and off the next)
- You did a search once when the extension was on sale, and when you went back another day, the sale was over
- But I have noticed that if you search for a domain, the automated system does try to get you to buy it later, even if you deleted it
I'll add a PSA (Public Service Announcement):
- Elephants may go extinct in this century (which is why the GD founder's elephant hunting was bad)
- People shouldn't ride elephants or buy elephant paintings:

...you basically have to crush an elephant's spirit, and almost kill them, in order to get them to do stuff like that. And their spines can't handle weight properly.
