Ask a Lawyer and Get Answers to Your Legal Questions
Well it will come down to the rules/policy and how they apply them across the board. If their policy is certain behaviors will result in banning and you can document others who have not followed the policy then you might have grounds for discrimination and a lawsuit.
I suggest you would want to consult with a local attorney who can review the policies and then write a letter stating that you are prepared to sue them for discrimination because the policy has not been applied across the board. Of course, you will need to present documented incidents of others who have done the same as you time and time again and have not been banned.
If you have further questions, you may post them here and i will continue to assist. Otherwise, please ACCEPT my answer as that is the only way I can get credit for my time and information in this matter. Thank you and good luck
