<nettime> admin note/RFC: 'antispam' services and nettime |
[we drafted this 'RFC' before we learned, from bruce sterling's message, that one of the services in question was spamming (some of?) the people who emailed its clients (probably via nettime) with what appears to be a unique URL. -- cheers, t] lately, a few nettime subscribers have signed up with one of several newish spam-blocking services that are generating what could, over time, become a problem for mailing lists. what follows is a rough explanation of how they work and why the nettime moderators think they're incompatible with -- or even antithetical to -- an open mailing list culture. we'd like some input on how to deal with them. the culprit service (which we won't name) works like this: (1) an email user subscribes to service and gives the details of his/her email account (login, password, popserver); the user also gets a chance to give the service a 'whitelist' of email addresses s/he wants to receive mail from. (2) the service then periodically POPs the person's mail and compares each message to the whitelist. (a) if the sender is in the whitelist, the mail is is passed on to the user; or (b) if the sender isn't in the whitelist, the service sends an automated response to the sender asking him/her/it to 'click on a link.' the webpage shows an obfuscated image of a short, random text, which the source must type into a field. once the source has done that, the mail gets passed on to the user. for mailing lists, this approach especially flawed for two reasons. first, if the user doesn't include the mailing list *and its admin address* ('nettime-l@' and 'nettime@', respectively) in his/her whitelist, the mail sent to him/her via the list spawns at least one 'click this link' response (to the sender) and maybe more (to the mailing list and/or its admin address). and a list admin can't simply explain the problem to the user, because the admin will get the same response. the only way around it is to 'click on the link.' for a list like nettime, which has almost 3000 people on it, this is a very broken system. moderating a list is quite enough work, but clicking here and typing there to route around subscribers' spam-blocking services is a chore caused either (a) by a badly designed system, or (b) by a user's sloppy configuration of the service. moreover, if services like this are widely adopted, the result will be mayhem. let's say that half of nettimers use them; and only 10% of them have misconfigured their settings (which is a reasonable number given the many error msgs we already get), then everyone who posts a message to nettime will be bombarded with 150 'click this link' messages. this would make posting to the list a huge nuisance and, in effect, kill the list. the nettime mods think this is a Really Bad Thing, and that the best solution is to discourage the use of these services. we contacted the people who run the culprit service, and they came back with a fairly substantive answer pretty quickly -- which is good. but if their business grows, they'll probably be less responsive. the simplest solution would be to trash these spam-blocking responses; but a better solution, we think, is to automatically unsubscribe anyone subscriber who misconfigures a spam-blocking account. if the person values nettime (or any other affected list), then s/he can sort out the problem; if not, oh well. we'd hope that these services would automatically whitelist everyone their users send mail to, because that would minimize the coercive aspects of these systems automatically. but, ultimately, that's their business. our business is keeping nettime as open and efficient as possible. but rather than impose this policy by fiat, we're interested to hear what nettimers have to say, on the list or in private. thoughts? the mod squad: andrea, felix, oliver, ted # distributed via <nettime>: no commercial use without permission # <nettime> is a moderated mailing list for net criticism, # collaborative text filtering and cultural politics of the nets # more info: majordomo@bbs.thing.net and "info nettime-l" in the msg body # archive: http://www.nettime.org contact: nettime@bbs.thing.net
