Same old "exploit", new use:
Achievement is 150 for the Title Master Carver.
In Lion's Arch there are overflows, you can carve each pumpkin once for each overflow. So all you have to do, is stand by a pumpkin and relog over and over again. Carve it as many times as there are overflows
When you've carved it for every overflow. Move on to the next pumpkin.
Every day or so new overflows are created and so new pumpkins to carve
150 total is account wide but each pumpkin carve is per character so add your alts into the mix or make new ones to continue the process if you run out of pumpkins on a character
