So if you're afraid you said something that crossed the line that could have offended someone, and upset that you got sent to gaol so you're going to be more careful from now on, doesn't that mean that the gaol served its purpose?
Edit: Another tip to not get thrown in gaol is to not defend yourself. It's a little messed up but I know of people who got thrown in gaol because they fought back. If a GM sees a report and goes into the logs and sees two people cussing each other out, it's not a good look for either one of them.
In the instances where someone didn't like me and kept swearing and telling everyone to report me, I just stay silent since their report is only going to look bad for them. I don't care enough to defend myself against random people on the internet who aren't worth my time who I'm never going to see again and it's a shame a lot of people take internet drama personally.
