Today, while replying to a message I received, I realized there’s no 30 ch_ar_ac_te_rs (sorry for typing it like this, but otherwise I couldn’t send it) requirement in messages.
As far as I know it only occurs in messages.
It only occured to me once and I’m too afraid to risk getting a punishment for bypassing the requirement intentionally, so I don’t know for sure how to reproduce it.
Sorry, didn’t know PMs only have a 10 char requirement.
