Is the distinction between knowledge after the fact and knowledge at the time of occurence of "bad traffic" not important?

I'm all for reducing bad traffic, but where does the line get drawn?

I've also been dealing with multiple abuse reports on Digital Ocean. Quite a few common abuse ports are already disallowed (in fact I have only a small white list); most of the problems originate from port 80.  And of course there's nothing we can do for encrypted web traffic anyway.

For what it's worth, I'm glad this thread came up and I've notified Digital Ocean of it in one of my support tickets.

It's really not up to lowly little me to decide whos traffic gets to pass.

And who is to decide what constitutes "bad traffic"? I am not a lawyer,
but in Germany one of the cornerstones of not being held responsible
for traffic passing through a Tor node is § 8 of the Telemediengesetz:
http://www.gesetze-im-internet.de/tmg/__8.html -- sometimes referred to
colloquially as the "provider privilege".

One only is free of responsibility if one neither initiates a transfer,
nor selects the transfer's destination, nor selects or modifies the
transmitted data. That's what "passing through" means.

According to two lawyers I spoke to, exit policies might already be
borderline breaking these rules for exit nodes, but the technical basis
at least guarantees that traffic will never reach an exit node that does
not let it pass. Now think of a firewall that interferes with transfers
once the data has already reached the exit node. Wouldn't you agree that
this means selecting/modifiying the transmitted data?

That's just one national law that I am aware of, I imagine other
countries have similar regulations in place. Any internet service
provider interfering with net neutrality risks lawsuits, because it is
not an ISP's prerogative to decide what traffic is "good" or "bad".
