You’re correct, you didn’t break any rules, you just got zapped because the automod thought u were sending an IP address.
Even then, saying Bank 3.0.0.0 is the same as saying Bank 3.0 but with extra steps.
Just be careful not to repeat things similar to an IP in the future.
Can you read the rules and quote the rule(s) you broke? Do this in a new reply, don’t edit your appeal. If you do not know how to quote the rules, read the guide How to quote the rules.
If you do not identify the right rule(s) that you broke or you do not know which ones you broke, I can make it clear.
