Several months ago, I learned, via the Chair of the Philosophy Department at British Columbia, that my old pal Carrie Jenkins had received an "offensive" package, and that the return address consisted in a mangled version of my Law School's address and a pseudonym attributed to me by a law blogger who had championed the idea that "law school is a scam" and whom I had mercilessly criticized for years (a short and sweet explanation of the whole background is here). That was weird, but I didn't think much of it, and no information about the "offensive" content was shared.
Then, in late August, David Velleman wrote to me as follows:

> A few people have received packages of excrement from someone using your law-school address and a name widely [sic] believed to be your pseudonym. I assume it can't be you -- which means that someone is trying to embarrass you. I don't know if there's anything you can do about it, but I thought you would want to know. Some of the recipients have reported the packages to the police.
