Anonymous remailers allow individuals to send electronic mail without transmitting any information that would enable others to determine the identity of the author.
Finally, the infrequent use of anonymous remailers by cyberstalkers should not pull attention from the negative effect that these tools can have on the law enforcement process.
And by combining the use of multiple anonymous remailers with use of widely available cryptographic techniques for "scrambling" messages, obtaining identification information becomes even more difficult - approaching, many suggest, complete impossibility.
In a move that sent shock waves across the Net, many of whose denizens believed that anonymous remailer technology was somehow foolproof, CoS representatives in early 1995 marched in to the offices of the Finnish police and managed to obtain a warrant authorizing the police to search the anon.
Cybercommunities have also conducted online discussions of appropriate behavior, and imposed sanctions on violators, in the controversy over anonymous remailers.
One might propose that the international community prohibit anonymous remailers.
As the tortured history of anonymous remailers indicates, net users have their own methodology for determining what is considered appropriate behavior, and they tend to favor tolerance rather than strict accountability.
Furthermore, commercial services, including commercial anonymous remailers, must know who their customers are in order to bill them or their legal representatives or agents.
Even if anonymous remailers are tolerated because they provide a useful service or are suffered because there is no meaningful mechanism for enforcing a prohibition against them, technological means for blocking messages from such servers still exist.
