The fact that you got away with it for a long time doesn’t mean the name wasn’t in violation.
They do not create a master list of all names that are forbidden, and then allow clever people to get away with finding new offensive names that aren’t on the list.
If you have a name that’s even mildly offensive, you should have another name ready for when you get the inevitable forced free name change.
The fact that you have gotten multiple suspensions tells me that you’ve violated this rule at least 3 times. The penalty for re-using an offensive name is suspension. You deliberately broke the rules.
