to an earlier backup version. And the HG visitor was not logged in
at the time.
So I think items in world can create "assets" in the databases that
are not garbage
collected when the assets are deleted or returned. hence it would be easy for
someone with a script or generator to create millions of such assets and ruin
any grid even if it just had one tiny patch for visitors to rez and
unpack boxes.
I see another possibility : rezing a box with a huge inventory. The
HG transfer may end well after the visitor has left.
There are few ways to create assets programmatically :
osMakeNotecard, osDrawImage , osSetDynamicTextureData and
derivatives, osNpcSaveAppearance. Not sure our spammer is smart
enough to write a database-spamming script, since he doesn't know how
to do auto-reps (the spheres i've seen on Fleep's grid were not
scripted).
