Just my opinion, I think if you report an establishment, the time frame can be much longer. I can't imagine the establishment changing too much aside from the girls. But if the place trains the girl right they usually will give a similar level of service. Walk-ups on the other hand are more time sensitive, since the girl is most likely gone after a couple of weeks, but if you have their contact/location then that timeline extends as well since bros can still find them. For less reported places, like your Bali trip for example, I would love to read about since I'm always looking for new places to go
Of course if you have a great story, timeline doesnt really matter either. I think many members here would enjoy a good read regardless of how long ago it was
In short, for me personally, anything other than a random usual walk up where the girl is long gone with no contact is the only thing not worthwhile..
