Lmao. Who are you? Do you even know how respected Darkstar is in this forum? Darkstar basically tried to help you understand the meaning of spam in a basic way and you want him to elaborate? Really?
Nothing bad about that. There's no easy way to make a definition of spam that covers everything, and it can be highly subjective so I don't have an answer. He did cut out this part though:
Spam is "irrelevant or inappropriate messages sent on the Internet to a large number of recipients". Basically any post that doesn't contribute to the thread.
