I am fairly sure it is a coincidence. I have blocked
a couple of user
names with the p word . It's just I found it hard to believe that no
body caught it.
Caught what? You mean that the vandal was never blocked? They stopped
vandalising on their own, so I suppose there was no need. Warnings
should have been issued, at least, but it's not unusual for people not
to (I've forgotten myself on occasion).
