just by getting more badges than Badumsquish
Badumsquish has pretty much every regular badge, every time-limited event badge (April Fools, collabs, …), some special badges (Derpibooru Premium, Squirrel, …) and even a unique GMHAA badge.
As far as I can see and unless I’m missing any rare badges, the only non-unique badges missing are:
- Since the Beginning, The End wasn’t The End (Not obtainable anymore.)
- Mystery Badge #1, Duck (You don’t want those.)
- The 1%, From the Night, Daring Do Dakimakura (Theoretically obtainable, but pretty unlikely.)
- Thread Starter, Cool Crow (obtainable)
If someone actually somehow manages to get more badges in an attempt to troll the devs (and we just established that wouldn’t even bother them), then…
