No longer a newbie if your PFP has been changed from the default, and you have done at least three of the following:
- returned following a ban
- appeared in at least two @BakedBanana images (your PFP, anyway)
- received props from @Manko-sensei for your yuri reading list
- started a thread that has hit 100 posts
- did an AMA thread and you responded 'pie'
- placed in a contest (minimum participants: 5)
- rigged a contest (minimum participants: 10)
- placed in a contest you rigged (minimum participants: 2 - you get credit for being a ballsy bastard)
- received a positive reaction of any kind from @Hikineet (seriously, this does happen)
were the victim of a @Baronoflight strike fest [no longer attainable]
- claimed a post with a number ending in three or more zeroes
- found your way onto any of the four full length leaderboards (one of those is really impressive) (additional point for top 5)
- had an exchange with @pandascepter
- made a Gal☆Cleaning! reference
- paged @HelperHand to respond to a post on @MangaDex's account
- confused @DavidianMillerian (half credit - it's not hard)
- got at least six notifications from @athayanezant responses to a profile post (again, half credit)
- have been told to go to sleep by @Angry_Panda
- engaged in a haiku duel with @EOTFOFYL
- witnessed a nuke of a member by a mod (suggested by @Bartolumiu - IYKYK)
(edited to add 'no default PFP', 'additional point for top 5 leaderboard position', and 'haiku duel')
(edit 2 to add 'witnessed a nuke')
