It is a fine line to cross. If you cross it knowingly, you might find yourself banned. Personally, I am not sure where the line goes exactly. The safe option for you is to not post stuff about area explore items at all. The ban decision depends of how you come off to the VIPs. If one of them interprets you intentionally talking about area explore items as malicious intentional revealing of game secrets, you might find yourself banned. Possibly for medium or long time.

The only simple moderator guideline I can give to you is to not talk about area explore items at all. Rule 8 violations happen gradually and at some point, the treshold is crossed and the ban decision is too case by case to give you better guideline on what is tolerated. Just assume that we have 0 tolerance that slips in inconsistent fashion and don't post about them. This way you don't get banned.
