Nigerian scam >>Spam Varieties

Spamming remains economically viable because advertisers have no operating costs beyond the management of their mailing lists, and it is difficult to hold senders accountable for their mass mailings.

1. Unsolicited Bulk Email (UBE)

2.Unsolicited Commercial Email (UCE)

3.Mail bombing

4.Flaming

Mail with matching content sent to many recipients who did not ask to take delivery of it is classed as UBE. This form of Spam was considered to be the most common form of email abuse until UCE

Alike to UBE but the content has profitable information. The dispatcher will have obtained a catalog of email addresses from an association that collect this information. They may have obtained the catalog through completely legitimate means, for example by purchasing it from such organizations. It is now a legal requirement in the UK for all organizations who advertise to individuals to ensure that they do not send communications to people who have specially requested to not take delivery of this information. However, where consent to communicate has not been starved of; they are complimentary to market to persons. The UK Government is currently reviewing this ‘opt-out’ loom in line with other EU countries as they consider whether to move to an ‘opt-in’ model: Where an organization can only drive marketing communications to an individual when they have the explicit authorization of that person to do so.

For mutually UBE and UCE spam, computerized software exists that is able of sending millions of email e-mail per day. The sum of bandwidth, storage space, and time that these mails consume is considerable. It is not the dispatcher who pays for these costs (unlike traditional direct mail), but by the Service provider the messages are sent through and eventually the receiver. UBE is seen by many as an utilization of the email scheme for proceeds and by some even as theft.

This is where a vast quantity of email is sent someone in order to overload their mailbox, depiction it and its host system useless. This is termed a Denial of Service (DoS) attack.

An additional form of this kind of assault is when the victim's email address is put in the 'Reply to' and 'from' lines in the header of the spam email. The victim is then swamped by thousands of replies. This has the same effect as a normal DOS attack but is harder to trace; mail headers are vital in tracing the individual responsible.

A third type of mail bombing is where the victim's email address is sent to hundreds of mailing lists. Website administrators have now started to use confirmation emails that need to be returned for a user’s payment to be valid. This in itself is can be seen of nuisance value.
