I'm concerned with this new Code of Conduct system, I understand having smart and respectful people is nice thou, It feels quite restrictive or highly PC. like harassment for example, the person might report that person for saying mean words, while others just seeing criticism. So demanding people to be nice is fine but can be highly limited to freedom of speech.

I can see you want nice and friendly people thou you can get highly authoritarian and out of control on censoring people, simply for offending someone's feelings. This may get a bit SJW if not careful.
