On blogs and Internet discussion forums, when participants use the SGML-style tags popularized by HTML (or sometimes BB Code-style tags) to accentuate their messages.
Sometimes these tags can include attributes such as <flame tone="angry">...</flame>.
Oftentimes the opening tag will be omitted and only the closing tag will be there, as a kind of self-conscious lampshade hung on the preceding flame/rant/etc. It is also used to show that a sarcastic rant mocking the opposite side of some debate is just that.

</unsubscribe> is occasionally used on Usenet to indicate that one is unsubscribing from a thread. However, the proper use should be either </subscribe> (to indicate that the subscription is ending) or <unsubscribe /> (XML empty tag to indicate an unsubscription). It probably means, though, that the person has just finished the process of unsubscribing. </justifyingedit>
