I don't think you really got hellbanned, Google captchas have just become extremely buggy in recent months. Whenever I have to solve one it always takes me a few tries, sometimes a dozen or more, and I usually triple check whether I've actually selected all the traffic lights/bicycles/chimneys/whatevers before submitting...

(Alternative hypothesis: If you solve a captcha correctly, they intentionally give you a few more, to get more good data for their AI algos.)
