Here; an excerpt:

James Grogan, chief counsel for the Illinois Attorney Registration & Disciplinary Commission, told the ABA Journal that state supreme court rules bar him from confirming or denying that a probe request was filed. Speaking generally, he said Illinois and a few other jurisdictions have initiated cyberstalking investigations of lawyers in the past.

It's been curious to see dybbuk's various defenders (including some posting at the ABA site) claim that Professor Leong's allegations aren't accurate, yet they are all documented with screen shots of the postings in the complaint.   And it appears to be true, and easily verifiable with search engines, that dybbuk's most extended ridicule and abuse of tenure-track law faculty, in particular of their scholarship, has been directed at seven individuals, two minority men, and five women, three of them also minorities (this includes Prof. Leong).  Dybbuk has, to be sure, occasionally delivered passing insults aimed at white men (even me, but no surprise there!), but none of them that I have seen (and I have seen a lot) have been subjected to the extended cyber-harassment dybbuk visited on these others, all of whom are women and/or minorities, as Professor Leong claimed.  Why the scholarship of female and minority law faculty warrants special abuse by this dybbuk character is a question that perhaps the Bar investigation, if there is one, will illuminate.  It could simply be coincidental, and not a matter of gendered or racial animus.  Or perhaps it will turn out that he is more of an equal opportunity harasser of law professors than the evidence so far suggests?

In any case, it's good to know that the Illinois Bar does sometimes investigate these kinds of cases.
