Update: Last week I received an automated response from email@example.com saying " Your account and/or IP are currently suspended from accessing our services." Then listed this link to appeal the suspension:
It just basically asks you if you agree to the terms in several different ways. Under the "Do you know why you were suspended?" question, which is a Yes/No question, they do not offer a "No, I do not know" option, but they probably should. The whole thing feels like nonsense, frankly.
So I filled it out, and about a week later I got this message:
"Unfortunately, your account was mistakenly flagged as a bot account and subsequently suspended. I’ve gone ahead and reversed this suspension on your account, so you are free to use our services once again.
Apologies for the inconvenience and have a pleasant day!"
So my account is back to normal, I guess. But the wind has been taken out of the sails for sure. I feel like spending any time or effort on Twitch is completely wasted given that it can be snatched away from you arbitrarily, or by overly aggressive automated ban hammers. This could happen to anyone, and it took weeks to be fixed and there's no guarantee that it would be fixed at all. I guess this is how life will be when everything is a digital subscription service...don't get me started on THAT.
Anyway, I'll probably resub to EZA just to support them, but will probably be less active. Thanks to everyone here who offered advice, assistance or commiseration. Best community on the Interwebs.
