I think it's hypocritical for a public figure to talk about 'opsec' so I never bring it up, but people sure want to take opsec advice from criminals who browse and register accounts on clearnet forums after they've been taken down by law enforcement several times, chat through Telegram and Discord, have a Twitter account and coordinate their activities on an iPhone they likely text their mom and pops with...
While you could do the above in a way that makes you non-attributable, the margin for error just seems so high... I don't think I'd take it.
It makes me wonder if the only major prevention against such people being caught is just that their adversaries (the cops) aren't interested in them. Moment a big company gets hit, you see a disruptive response follows. This would make sense since attribution or discovering responsibility of an attack doesn't prevent an attack, building defences does.
