This suspicion is founded: many of Graeber's claims are also false; in particular, Delong provided a litany of elementary falsehoods in Debt, in which Graeber's inaccurate claim about Apple is merely of especial characteristic inaccuracy--but that's beyond the scope of this post. Zooming back out, if one leads and ends with hateful insults which they cannot justify, that ought to be viewed with deep suspicion. No, DeLong is not a "con-man" who "suckers" people because he wants to call out a book which he feels, and can earnestly argue, is deeply wrong.
Near the end of this long, screenfilling rant, Graeber claims he has been trying to "ignore" DeLong. I didn't know such fits of apoplexy were how you ignored someone.
Graeber went into detail about why DeLong was impossible to ignore, including DeLong apparently creating a twitter bot to attack Graeber (!!).
Graeber's fit of apoplexy wasn't just in that one HN comment. His "ignoring" DeLong was an uninterrupted train of obsessive, one-sided, and often bizarrely misdirected anger and insult. The only "ignoring" was that Graeber, in all his raging against DeLong's trollbot, did not bother do any raging in the form of citing facts or other defense. As DeLong puts it:
> Graeber, of course, makes no attempt to defend his claims in his chapter 12. He doesn't because he can't. Chapter 12 is in fact riddled with errors.... It really appears to be just too easy for people like David Graeber to imagine that they are in a two-month extended conversation where there is a human mind on the other side, when actually they are just the bird pecking itself in the window glass[1].
That incident was a piece in a longer flamewar in which Graeber, essentially, behaves in the obsessive and intellectually bankrupt manner he accused DeLong of behaving.

As for the actual Debt: The First 5000 Years book, it's engaging, thought-provoking, less opinionated than I was expecting and right about a lot of big things. But his critics aren't wrong that it's also wrong about a lot more small details than the founding of Apple Computer (one I'm surprised none of the academic economists scrutinising his book picked up on: he describes Treatise on Money as Keynes 'most famous work' which is akin to calling Wings Paul McCartney's most famous band. That's particularly surprising in the middle of a passage about Keynes' work which is actually well-informed). Still think it's worth reading for people vaguely interested in the subject matter though.
That's what Gell-Mann amnesia is, really: we believe what we want to believe, and forget the quality of the source.
> I've honestly tried to just ignore the guy, hoping he'll eventually go away, but since he won't, I guess I have to explain what's really going on.
As I described elsewhere, Graeber is also lying when he said he made any serious attempt to ignore DeLong at all.
