Whenever I find an obnoxious captcha, I just leave the page after two failed attempt (not really failed, but you know how it is, the system decides that you have to repeat the captcha again).
The problem is with certain services (like GoG) that I've had for years but that lately don't want VPNs because reasons and will keep forcing the captchas indefinitely even when I'm login or redeeming a game. Those are the worst, and honestly? They are only harming themselves with them. I don't buy from them anymore because last time I wanted to login to buy something, I had to go through a least 20 captchas just to login (and, of course, the audio captcha wouldn't work because that would make me "skip" the whole ordeal). After that I decided to go to gog only if there is a game that they are giving away and I really want.
I've been diagnosed at the tender age of 36, because my lovely parents didn't give a fuck about all the signals and the teachers "hints".
Up until then, it's been hell, and I'm not exagerating when I say that I don't know how I made it this far in life. When you are one of the "lucky" ones that only suffer from what is now called "functional" autism (aka there is no cognitive disability), you struggle with most social aspects, you torture yourself thinking you are weird, you hate yourself because it's obvious (only for yourself) that there is something wrong with you that you can't understand.
A diagnosis is not a death sentence but an answer to what is happening in your brain to make it work differently. Now, I am starting to get help, I am asking for acomodations that make my life easier and I understand what is happening in my head. And most important, I'm not ashamed anymore when my "weirdness" leaks out because I understand it.
