Data Protection query

[Gerard Blake]

If my email address had been collected as part of an entry to an event, and I am then subsequently sent an email that has nothing to do with said event, is that a breach of the Data Protection Act which states:

Personal data shall be obtained only for one or more specified and lawful purposes, and shall not be further processed in any manner incompatible with that purpose or those purposes.

Also if it has been several years since I have entered an event run by that person and I am subsequently sent an email from the organiser, is that a breach of the Data Protection Act which states:

Personal data processed for any purpose or purposes shall not be kept for longer than is necessary for that purpose or those purposes.
