How unreasonable it is...

@_Lambo_16, read this.

<Alice> Bob, are you interested to join our team?
<Bob> Of course.
<Alice> Do you promise not to betray us?   <= I can type this within 5 seconds. **** the 7-second limit. Reduce it to 3 seconds, which I still think is a lot!
<Bob> Of course.    <============ Why can't one just repeat his sentence?
<Alice> Wwlcimr!
<Alice> *welcome   <============ you seriously want to disallow this and let the mysterious typos stay on our server?
<Alice> :)       <============  you wanna disallow the emoticons unless they are attached to long sentences? And then you plan to kill that again by disallowing too long sentences?
<Bob> :D       <============ don't tell me this is too short.
<Alice> :)       <============ do you want to force players to add a space at the end to allow typing this? Or you want me to play hide&seek with them and I have to use all sorts of methods like trim(), RegExp, etc. to catch them?
