I did saw them once promoting illegal fake passports and COVID-19 Vaccine certificates, or even something like what this guy is posting:

But that's just the things that i remember of seeing from them. Other than that, maybe some gambling websites and some kind of malware from dark web or whatever. But for the recent ones, these guys are promoting death spells for revenge and kill people, like, bruh, this isn't anime, this is real life!
