good to know. I logged immediately after the encounter and wondered if they would really 'investigate' things or if it was more of a matter of catching them in the act.

Many players get reported for "gravity" or "jump hacks" on the clock tower that are playing completely legit.
With that said, it's extremely unlikely that enough players filed a report that you rose to the top of ANET's priority list and a GM immediately came to observe.
Further, it's even less likely a GM showed up to observe prior to the annoyed player informing you that you were caught. (how nice of them!)
So, unless you put gZoom on "moon" gravity and were literally flying through the air so that they could capture a screenshot of it with the bug report (while simultaneously doing the clock tower jumps), I think you're probably OK.
With that said, I'm not aware of any delayed-blast bans. It pretty much happens within 30 mins for those whom I know have been caught.
