I have kind of changed my mind about this from what I said before. It still doesn't really matter but I dislike it for a few reasons:
- It's utterly pointless.
- I don't see what possible enjoyment you could get from it.
- It wastes resources on the site. (That's a fairly minor issue though, we have plenty of storage space and chat can handle dozens of people, so one person spamming on their own doesn't really hurt.)
- When people come onto chat all they see is just spam, instead of the recent conversation. It could be some people only left for a minute.
- Asking if you can spam is a stupid question.
In conclusion, you probably aren't gonna get banned for spamming when there is no one else there, as long as you stop when others enter the chat room.
