I don’t think the addon is the problem to be honest.
If you got reported and action was taken against your account enough times to be muted in game for 8 months ( that is 9 different mutes over the life of the account which adds up to like a year and a half of being muted ) then I think you are just a toxic person no one wants to play with , talk to or interact with in any way shape or form.
Even if the addon was banned I would suspect most people on your server probably already have you on their in game /ignore list.
Being that it is a classic server your reputation to the people on it matters.
