2016 will be updated to filter slurs out and introduce a warning system instead.
Each user will be allowed 1 warning before a ban, and bans will stack up.
The first ban will be 3 days, followed by 7 days, and finally a permanent ban.
Curse words will still be allowed. There is no plan to censor normal curse words.
2012 is likely sticking with the instant ban system, as we don't have the source code to add a filter system.
