Combating Trolls idea.

Discord should have a way of having the invite only allow those with a discord account older than 7 days (or a variable timeframe) to join a server.  Most trolls I see create an account and start bashing as soon as they can. 

I would ban them for having a 1 day old discord account as well a a 1 day server account but have doubts because it could be an innocent user new to discord just signing up.

That would slow Trolls from creating accounts just to spam malicious content. Especially time sensitive spamming or bashing.

I'd like to hear thoughts on this.
