speaking as a Random Site Member With Opinions, not as a forum mod:
- Our rules are not universally the same as other sites’ rules. If someone was banned from Chief Delphi for repeatedly posting profanity, they would likely be fine here.
- Relatedly: sites vary in how fair and objective they are. I’m sure that, somewhere, there exists a site that has manufactured legitimate-seeming reasons for banning someone who hadn’t actually done anything wrong. An uncritical policy of just banning anyone banned on another site would risk unfairly banning innocent people.
- Some people are capable of growing and changing over time. Imagine if every site had a policy of banning anyone who ever broke a rule on any site ever – people would essentially end up ostracized just for making one mistake, when it’s possible that they can learn from then.
- In the worst case scenario, we can just … ban the person who’s causing the problems.
