For the last couple of my resets in Enishi and another alternate account of mine, I have yet to run into the Curse Seal event or experience a "rare" drop of the ink itself.
I have ran into the Tattoo warrior but that is pretty much it...I have yet to see Baluski's bride as well.
Also...
May we not just have Oto moved up to village status once more? There are no forest to fight in there. There is no arena for anyone that is not born there...and that just leaves sitters who were Sound ninja's eligible.
If the server can handle the extra 'room' then why not keep it?
Edit: Correction. Not even sitters with Oto as their home upon their bios can battle in its arena. It is still up but totally non-functioning.
When the village changes occurred, Otogakure became a PvP-free area as a replacement to the map-only accessible Iwagakure.
So pretty much it's a place where one can be safe.
As for the battle arena there...well I don't why it is still even up there, it needs to be removed.
Edit; I taken the liberty of moving this topic to it's rightful area.
