You being a long time player and spending money shouldn’t protect your account from being actioned. This is just entitlement.
As for them losing a paying player… You leaving after being actioned once you clearly aren’t into blizzard games anymore so I’d say they’ve already milked you.
As for what you did considering you don’t actually talk about what you were actioned for and how argumentative you are I’m gonna side on you probably had a few bad days and went full tilt, got reported and now your on the copium.
Either way, least this shattered the illusion you owned things and you’ll be better for it.
