He was talking about actors who contribute to the system. See my other reply : https://news.ycombinator.com/item?id=46202319

I don't see how the article you linked is relevant at all to the OP and the topic of scams in general.

If anything it just shows how the leadership and allegedly well-meaning leadership chooses to ignore the issue.

Isn't it very likely that the malicious actors are part of the ecosystem and they contribute with funding? I'm not convinced that the scams and the casinos are an entirely separate fifth group (as opposed to a spectrum pyramid which might place say the Eth or Sol devs at the top). But even if they were, it's possible that the whole ecosystem and developers are benefitting from it?

It seems that the very nature of banks is associating and trading deposits and debts, so if more than half of the ecosystem consists of scams and theft, the other 'good' half is both benefitting and enabling the 'bad' half. Legislation is very clear on this, which is why we have KYC, money laundering laws, which are curiously enough the very social features that the supposedly "technological" innovations seem to do without.

In any case just ignoring the issue as a whole is a bit damning by itself, ignorance at best.
