It's easy to look at every single edit. I did it.
(Yes, Erik, Lir put in the link to good taste first,
after Clutch had put it on her user talk page.)
There's no doubt in my mind that vandalism was at work.
This is not name-calling; I do not say this gratuitously.
These sorts of changes to a user page are unprecedented,
and they were done repeatedly, despite admonition
from several other Wikipedians. Normally bannable.
However, we made an exception, because we hate Lir.
I don't hate Lir, and I was very tempted to ban Clutch. My previous oath to
avoid banning as much as possible would have stopped me, even if my lack
of developer access didn't.
