Just got a "You are eligible for this SPECIAL OFFER" email from GOG: with a button "YOUR 85% DISCOUNT". I clicked on the button and I am confronted with a page (And there is no captcha there to complete - probably due to my browser blocking it in some kind of manner.)

I have three issues with this:

1) Captcha is evil and should be purged from existence. Do not use.

2) You are deceiving with your Email. If it requires to submit to customer harassment practices (captcha) you should clearly state so in the Email.

3) I am logged into my account. There isnt a technical reason to use a captcha in this situation. There is no significant potential for abuse. You could just program this properly instead so that users dont have to mess around with codes.

It's certainly annoying and occasionally broken, but it's not evil. It's (flawed) tool to keep bots out. What is deceiving? You get the discount when you solve the captcha. Which is an annoying security measure and not there to especially harass you. Nobody loves them, and if it would work without, they would remove it. No store loves to torture their customers. Just because you don't see abuse potential does not mean there is no potential.
Bots can have accounts. Bots could mass-redeem stolen codes.

I already wrote whats deceiving: Putting additional hurdles between me and my 85% discount without telling me in the Email. And I disagree with the rest of what you wrote here. Just replace "captcha" with "DRM" and "GOG" with "Steam" or whatever other DRMed platform. There is no need for 'codes' here. GOG knows who signed up for their newsletter. If I have signed up for it and want the discount I am entitled to it. I dont see any serious abuse potential there. Adding captcha is just like adding DRM to a game after it has been cracked already. Its just there to lord it over customers. (Note that I am not saying that there are no use cases without abuse potential. Obviously however my use case does not require any countermeasures so adding a captcha to it serves no purpose other than being mean towards me.)

The newsletter contains a redeemable code. You can also give it away to someone else. No, it isn't. Not at all. Lol. You should really take your pills.

Unless they're getting paid to do it which is third party intruding and should be punished.

It's Google... you always pay with your data. I agree it sucks, and if GOG wants to use mechanisms like that they should host them themselves. Sadly everyone and their dog loads scripts from gstatic.com...

Which I didnt. Which GOG has the means to know as it is them sending this exact code to my accounts Email.

Edit: And obviously this (me clicking on MY Email to get MY discount to buy MY games into MY account) is the most obvious most straightforward use case. So requiring a captcha for it only makes sense if they intentionally want to screw customers or are incompetent/unwilling to do it properly.

The point of this thread here is to give negative feedback to GOG.

If you want to solve bigger problems - I think you are in the wrong place here...

Well, comparing a simple captcha to DRM, and accusing GOG to "deceiving" you will really help you to be taken seriously... lol. I don't think so.

Why, Hello!

Might I interest you in casting your vote against Crapcha here?

Thank you!

I totally agree about the captchas. I don't want to help Google build a profile about how to sell things to me that they will then sell on to other companies. The thought of them finding out so much about how to manipulate people is scary. I don't mind the inconvenience. I'd sooner do ten privacy respecting captchas each time than one Google one.

Captcha aren't a problem if they are properly made, but the google recpatcha should be removed from the world. They made it to stop bots, but actualy the bots are better than human to solve those google recpatcha.

What does that have to do with anything? GOG is a business. I dont see why they would care if their income comes from people whom they "take seriously" or people whom they "dont take seriously". The message (if that wasnt clear before) is: captcha => no sale + bad rep from me.

No idea what you are trying to say with this link.

Unfortunately I cant vote another time...

From what I have read they also use them to train their AI. I think it goes like this:

They take random pictures. They let the AI classify those pictures. They hand them out as captcha. Yes this means if you click correctly and the AI made a mistake it counts as your mistake. (And then they somehow use the human classification results as input for training their AI.)

Putting the issue of CAPTCHA/reCAPTCHA aside for a moment, let's dwell on this: It's not your discount, it's GOG's and the publisher's, offered to you (yes, with various conditions, some implied). They are entitled to put whatever conditions and qualifiers they like on the offered discount; you are entitled to choose whether or not to avail yourself of the offer. You are also entitled to complain about the conditions and qualifications of using said discount (ideally with more tact and less zealotry than you've shown here). But you are not entitled to receive the discount on your own terms.
