Now I have two questions about this zero tolerance thing and since it's on topic, I might as well add it here. 

If a member breaks one rule and gets a warning, but then later on they break another completely different rule, both felonies being very minor, would these members be receiving another warning for that specific break in the rules or would they just receive a full ban for it instead? 
IE: A member posts something like a biology picture about gentitles and is warned about not posting them but later on in that same day they get a little heated in an argument, nothing major but something that does need mod attention for them to stop. Second warning or full ban?
When it comes to warnings, are for all of time (or for as long as the mods remember) or after a certain/long amount of time would a member just received another warning? 
IE: A member posts some small bigoted remark and is warned not to... after a few weeks to months to a year they do it again. Warning or full ban?
