For me, brigading means that somebody posts on Facebook to get his followers to reply to something he didn't like on Twitter. Somebody brings his brigade to influence an opinion. If now these followers stay on Twitter to spread the word about something they genuinely like, it's not brigading anymore.
Now if people that follow nostr:npub12rv5lskctqxxs2c8rf2zlzc7xx3qpvzs3w4etgemauy9thegr43sf485vg chime in where he chimes in here on nostr, that might also feel like brigading but I don't see that happening to any degree that would feel unnatural. I follow several eToken developers and clearly they spread the word but extremely respectful and not in a way that would drown opposing opinions which brigading often does.
