How do you know these people aren't contacting zavvi about it too?
We're are all here for the same thing so people explaining their situations helps in that way. People know they aren't alone on the matter when its occurring to others
Humans love a good ol moan and a worry. if your British then it's in your DNA (as you should know)
A good example is the nova age of ultorn, a big number of us had our orders on the same flight. It's been over 2 weeks since that flight left Korea with no update on the other side. A bunch of us have been worried, some have contacted nova etc etc and vented on here.
Then this morning around half of those people randomly had the update to say it was in London and being processed whereas me and the other half still haven't had movement yet we was on the same shipping flight.
That's worried me because others have had updates (just like your example of people getting worried that others have their GB items before others - it's natural to wonder what the **** is happening and considering we are all here for the same reason waiting on the same time we come to here to talk about it and vent)
