Are 100% GM scrolls going to disappear after event?

Of course they won't disappear. They'll be just like Chaos Scrolls; they'll be rereleased so many times that they'll eventually just get added to the drop tables. They'll be featured in the "NEW GACAHPON@@!111" notices for the next year.

Nexon America would never put any item people Gach relentlessly for in monster drops. Did I hear someone say Stonestooth?
