There were some art projects in 2017. I remember two of these: SCAM Token and HODL Token.
Wow. Like: "Invest in SCAM"? That sounds, you know

Like advertise of any ICO in 2k17
It's good that now this advertisement will be banned
Bans don't prevent them from searching other ways.
They will not be needed, all the hype around the crypto currency will cease
That's what I'm saying. You ban them in Facebook, they go to Telegram. You ban them in Telegram, they switch to TOR. Now go ban them there.
