tips to follow..
just dont send 800k bunches over the TP
and if you do, dont have numerous transactions in the course of a few days, its alot easier to stay off the radar that way
you can use the shop method, which in my opinion is safer, but you would be transferring smaller amounts, so it is much more tedious
the BEST way to transfer large sums of NP is to buy an UB petpet, attach it to a crappy pet, put it up for auction.. buyer adopts the pet, and sells the petpet for pure
that last method is by far the safest, and the chances of getting iced for it are probably the closest you will ever get to 0
other than that, dont get anxious, everyone deals with the same stuff when it comes to moving around neopoints, no one is ever safe, the fun is just not getting caught
