I don't get what you mean by that. Everyone does it so it's OK?

No - scanning without consent is abuse and anyone doing this is malicious regardless of what they tell themselves or anyone else.

I am not saying its OK. I am saying it is probably not this crawler that is hammering your site, and definitely not only this crawler. I specifically mentioned malicious attempts at ssh logins.
