Quite a bit of FUD here.

Now i would like to see those maths

They started selling 43khash at a time, new shares are 100khash each and sold in batches equivalent of 183mhash.

It's been validated that most orders go unpaid etc.

The new 40k0 packs resulted in a few dozen ghash indeed by themselves. That is huge, seeing the total network is right now 1 426Ghash. several % of the network there alone.

EDIT:
This is explained: https://litecointalk.org/index.php?topic=22708.0

Now assuming he has had 10k "orders", out of which 80% are paid which is 8000, and if each is the latest 183Mhash pack that is 1464Ghash indeed. But alas it is not, most of them are not actual sales etc. because # gets larger with each comment, page etc. so it's probably more like 4k paid orders, out of which most are sub 100Mhash. even at 4k & 183Mhash it results to about 732Ghash. Still a huge number tho.
