It's not just crypto projects, every tech startup is doing an ICO to raise funds because it's the new meme and it is (or was) unregulated.
2018 was a crazy year for bitcoin

You said it is the new MEME ..lol that got me cracking, they really took advantage of it!
they could create a council that just help regulate the ICO space instead of letting anyone with a website do an ICO
It could be a decentralized union who votes to approve any startup for an ICO, that way prevent lots of crappiness
