We have a pattern abuser showing up on English

denial of service attack on the image servers for en.wp.
The pattern is easy to spot, once they do it, but "easy" in this case
is normal reaction time of admins / alert users, most of whom haven't
seen the pattern up close to know what's going on.
Is there anything that can or should be done ahead of time, at the
site operations level or developer level, to try and keep the presumed
end-case massive DOS attack on the systems from succeeding?
They're telegraphing their actions out pretty obviously, practicing
for what I strongly suspect is coming. But I don't know that we can,
with in-wiki tools, find them / block them out effectively enough...
Thanks for the report, we'll keep an eye on it. I don't think there's any
urgent need for action, and I don't think there's a need to advertise his
actions and thus give him more satisfaction than he deserves.
