Hmmm... let's pull out the old dusty, voluminous copy of The Official Forum Rulebook
that has been handed down from generation to generation of moderators and see what it says...
Definitions of SPAM:
a disruptive, esp. commercial message posted on a computer network or sent as e-mail.
What is SPAM?
- when you double post or cross-post the same message in multiple forums
- when you mass-PM or mass-email multiple members of this site the same message
If you engage in any type of SPAM; you will be permanently banned, no questions asked.
Spam can sometimes include people making random, unconstructive/purposeless comments in threads. This can be quite annoying when it disrupts the flow of a thread and makes it unnecessarily long. Sometimes people can go slightly off-topic in a good-natured way, but others just make posts that are silly and not worth reading.
On an Islamic forum, it's even more important to be careful of this, because if the post has no purpose, then it opens the door to fitnah where brothers and sisters can idly chat in such a manner.
