This sort of thing has been going on for many years. I used to refer
to it as "mobbing". As nearly as I was ever able to determine, the behavior
is an unintended consequence of hidden services. I found that I could greatly
reduce the frequency of occurrence, but *not* to zero, by setting
HidServDirectoryV2 0
in my torrc file. My tentative conclusion was that the majority of these
events are cases in which a relay has been selected as an HSDir to which
a hidden service descriptor has been posted for a very popular hidden service,
so by refusing to be a hidden service directory mirror, those cases can be
eliminated. I never had a very satisfying hypothesis to explain the remaining
minority of cases.
