achow101 is the best nominee to this list, he can accurately point out and correct mistakes from the member's replies and posts in the D&TD Board.
Shouldn't he then also get the Bitcoin Core developer badge?This badge
refer to Bitcoin-Qt core developer, right? And achow101 one of on the list:https://bitcoin.org/en/development
But I can see that badge on achow101's profile, even in in Dev&Tech. Can it be disabled?
Edit:
It's clear enough, didn't all of the core developer got those badge.
