Ok some of you faggots are a bit slow, so I'll give you the MetalArchives 2022 guide to NSBM.
Step 1: If you suspect a band are a bunch of evil nazis, look them up on MA and check whether they have some problematic lyrics under lyrical themes. Examples include National Socialism, misogyny, anti-Islam, anti-Semitism, nationalism, patriotism, racism.
Step 2: THIS IS IMPORTANT! This is the reason the guide was updated in 2022. Check the "country of origin" section, there's 3 possible outcomes:
a) If it IS Ukraine, then they're heckin' valid, DO NOT ATTACK!
b) If it IS NOT Ukraine, commence kvetching.
c) If it's PUTLER'S R*SSIA, dial your kvetching up to 11.
