Hashcash is a cryptographic hash-based proof-of-work algorithm that requires a selectable amount of work to compute, but the proof can be verified efficiently. For email uses, a textual encoding of a hashcash stamp is added to the header of an email to prove the sender has expended a modest amount of CPU time calculating the stamp prior to ...
Webhooks are "user-defined HTTP callbacks". [2] They are usually triggered by some event, such as pushing code to a repository, [3] a new comment or a purchase, [4] a comment being posted to a blog [5] and many more use cases. [6] When that event occurs, the source site makes an HTTP request to the URL configured for the webhook.
For example, by simply inputting the word "porn" into Google's search engine, spam messages can open up several sites related to the word "porn." These messages make it very hard to trace the spammer as the search word(s) make it appear as if the spam receiver entered the word themselves.
Naive Bayes spam filtering is a baseline technique for dealing with spam that can tailor itself to the email needs of individual users and give low false positive spam detection rates that are generally acceptable to users. It is one of the oldest ways of doing spam filtering, with roots in the 1990s.
Spam reporting, more properly called abuse reporting, is the action of designating electronic messages as abusive for reporting to an authority (e.g. an email administrator) so that they can be dealt with. Reported messages can be email messages, blog comments, or any kind of spam.
Duck typing is similar to, but distinct from, structural typing.Structural typing is a static typing system that determines type compatibility and equivalence by a type's structure, whereas duck typing is dynamic and determines type compatibility by only that part of a type's structure that is accessed during runtime.
The passive method of adding random words to a small spam was ineffective as a method of attack: only 0.04% of the modified spam messages were delivered. The active attack involved adding random words to a small spam and using a web bug to determine whether the spam was received. If it was, another Bayesian system was trained using the same ...
A spambot is a computer program designed to assist in the sending of spam.Spambots usually create accounts and send spam messages with them. [1] Web hosts and website operators have responded by banning spammers, leading to an ongoing struggle between them and spammers in which spammers find new ways to evade the bans and anti-spam programs, and hosts counteract these methods.
