I have some points to make about this:
1) Yes I agree that OSBot marketing and runescape marketing are different. This is how I perceive the chat rule basically -
Advertising your market in OSBot thread per 30 minutes, example: Check out my shop here!! Best prices!! Need fast powerlevelling services!! etc.
Asking to buy something in OSBot market per 30 minutes, example: Buying 30 day membership, PM me! 10 mins later, Buying 30 day membership, PM me! - Ban.
Now, I understand that people do have an autotyper for every 30 minutes, so they say, see my shop, bla bla bla, but then randomly they will say, hey anyone got 100 iron bars I can buy? Now with that I don't care at all because it's understandable. However if they keep saying, anyone have 100 iron bars, or anyone selling 100 iron bars, then I will ban you.
I do agree that some of the ChatBox Mods do need to chill out a bit, but it is up to their discretion as to whether or not banning someone, as we made them chatbox mod for a reason. However we have implemented a new rule that we must warn you first (I do this anyway because I know i'll just unban you once you appeal anyway). So yeah, thats my 10 cents.
