“Shout messages will be limited to 150 characters max.”
I feel that 300 characters max is more reasonable BUT with a delay of around 30 seconds or more each message. There could even be a rule of not saying the same previous message. The limit on characters is good as it doesn’t fill the entire shout box but once the bots start shortening their messages it wont fix the core problem which is massive lag during their ■■■■ storm spam messaging. In my opinion, if there is any level limit to being able to shout in chat, it should be around 20. If you combine all three of these things, you will see much less gold selling bot spam.
The only problem that remains after that would be if the bots start whispering. And that’s a huge nuisance.
