Exactly what do you think it harms posting "empty strings" to warrant the wasting of services resources?
As i said in the first post, it is related to trivia bot and would be bit complicated to explain now, in short it allows cheating. It is not wasting of resources any more than setting a single kicker or global server badword if you go that way. (many and in my opinion pointless are already included as default so one more wont do harm)
Secondly, if I remember correctly badwords works off of glob for an entire string and to set a space character as a bad word would kickban everyone for every single sentance they type.
Exactly as you said, and that would be pointless. The meaning of my question was, and maybe holes in my english knowledge (not my language) prevents me to explain this better, is there a way to prevent posting an empty string (spaces only) in the channel but to allow posting normal sentences which of course include spaces in them. For example you can post "_blah___blah_" but can't post "_" or "___" or "______" etc where _ is space.
My advice .. don't be such a tyrant!
Indeed my bad, i constantly forget how lack of knowledge tends to envoke vanity plus majority usually judge other people starting from themselves. As you obviously can't help,my advice is to close the topic and show who the real tyrant is. Bye.
