I have had the same problem but not recently. I would usually reply with a 
standard "someone behind the firewall requested this". Usually they go away the 
biggest issue is if your provider keeps track of these "problems" they may 
cancel your account.

I actually stopped contributing to the pool for a while because of this 
problem. As my provider was threatening to(and eventually did) shut me off. 
Luckily I have a much better provider.
Thanks,
will

Subject: [time] NTP replies accused of being abusive
 
My NTP server in the pool sends out the time to whoever asks for it.

Problem is, some folks firewall off my replies, and even worse when they
see my replies of what time it is coming back, they report these
as network attacks on their machines/networks from my network to
their network providers, who tells my network provider, who then
makes me fill out a form saying that I am not going to abuse the
network anymore.

So far I've been blowing these off, but for some reason this really
has picked up over the holidays and now I apparently have to explain
multiple times a day why I'm sending traffic to port 123 at different
machines when they ask me what time it is.

Has anyone here come up with a form-letter that explains that no, these
are not network attacks (for some reason many of the complaints I
get specifically mention "ntp overflow exploits")?

Strangely enough, the form-letter that I often get from ISP's
has a link to the "ntp overflow exploit" info page which explains
that this is really a false positive because ntpd has no known
overflow exploits...

Tim.
