Strictness doesn't really come into this - all this would do is make it so that people couldn't over-advertise at all and they'd have a built-in timer to do the recording for them. If this comes across as strict, that's a problem with the rule, I think?
It doesn't change the strictness at all, to be honest, it's still the same rule but taking out the mistakes and favuoritism of mods and users. :)
"Please use ad chat for adverts! :) thanks"
Doesn't seem too strict to me? Feel free anyone, to correct me if I'm wrong here.
This suggestion comes from another site that I play that uses the same method and it works extremely well there. Everyone just knows to use that chat channel for ads and it keeps regular chatting uncluttered since you know to skip over the other colours.
