I just tried this and it's pretty nuts. First of all, their implementation of reCaptcha just didn't work at all for me in Firefox, and I had to switch to Chrome to even submit the request. (Captchas on CCPA request forms? Seriously?) Then, in order to verify my identity, I was asked to submit a copy of my driver's license or passport plus a current photo within 24 hours (after 24 hours I'd have to start over). I haven't made a ton of CCPA requests (probably 10 or so) but this one is by far the most onerous (not to mention that it seems like it might simply not be possible if you don't have a driver's license or passport)
