As someone who added CAPTCHA to their own platform recently after resisting for years because of how much I hate them, I have to tell you that the unfortunate truth is that eventually bad actors ruin the party for everyone on every platform.
CAPTCHA is necessary for the same reason locking your car/house is necessary. You can probably not do it 9 times out of 10 and it will be fine, but then that 1/10 happens, all your stuff gets stolen, and you start locking your doors 100% of the time.
