Re: NSPs filter?

[Chris Woodfield <rekoil () semihuman com>]

IMO, Commercial ISPs should never filter customer packets unless 
specifically requested to do so by the customer, or in response to a 
security/abuse incident. 

Consumer ISPs are much more likely to have clauses in the AUPs that are 
enforced premptively via packet filtering - antispoof filters (honestly, 
antispoof filtering is, IMHO, the one expection to my "commercial ISPs 
should not filter" rule), port blocks to prevent customers running 
servers, outbound SMTP blocks to off-provider systems to stop direct-to-MX 
spamming, ICMP rate limiting, et al. All of which are fine by me as long 
as they clearly assert their right to do so in their AUP - that is, as 
long as there's a comparable provider I can use instead.
