Is this really from GOG? If it is please stop. If not, any idea what is causing it?

looks odd

You don't appear to be using an ad-blocker.

That is not really the issue. No ads should appear unless it is put there by site administrator. It is either something GOG agrees to or the result of some sort of nefarious deed. (site hacked, malware on my side, etc.) An adblocker might stop it from showing, but would not solve the underlying problem.

Indeed, this looks phishy and hacked. I don't think GOG puts foreign ads on their page, so malvertising in the classical form isn't likely. "Give us your phone number and we'll gift you stuff"... riiiight, more likely you'll get messages like "your account credentials are neded for verification, oh and please disable the 2FA, and whilke you're at it, hand over your credit card data as well, please". Though of course, given the current pathological desire corporations of any sort have to get their hands on phone numbers, it's not totally impossible that some bright mind at GOG thought this would be smart.

There might be something going on with GOG ATM, since using Galaxy, when I try to check / redeem a code (be it game code or be it newsletter discount), I occasionally get an odd pop-up that blocks the actual redemption dialog until clicked outside of, which makes it go poof. These pop-ups don't show the entire content as they're too small for it, but don't have such phishy-looking stuff as the OP. Instead, they're GOG promos like the warhammer freebie and such, looking like it's supposed to be the store promo page instead of popping up on key redemption, which is one of the last places to want such stuff.

'NO SPAM'. (O_o)

Whether this is from GOG, or, one of its 'partners', this form of marketing is unnerving. 'tailored promotion info' -- Hopefully, if authentic (dubious, but, this is GOG, after all), this entails games similar to purchased and wishlisted titles, and is not based on user 'behavior' data acquired through tracking search queries and game page visits.

With GOG newsletters sent via electronic mail, there is a fair bit of distance between the customer and the 'content'. With SMS text messages, it becomes all too immediate and intrusive.

Histrionic scenario (in the same vein as GOG newsletter titles of the past):

[22:04] *ding*
*checks phone* (-_-) "GOG, again...?"
*disconnects phone battery*

Seems legit.

By the way, GOG's uh...limited function forum doesn't support image tags.

Seems about as legitimate as a bridge business in the great Australian Desert.

Why wouldn't it be?
• We know they added ads to the redeem page, if you opted in to the advertiser cookies.
• We know they tested asking for donations on the checkout page.
• We know homepage giveaways now automatically sign you up for newsletters and pass your data along to their "trusted partners".
Why would offering a freebie in exchange for texting you weekly ads be too outlandish to be believed?

Because this is a fallacy. When someone makes a claim, each claim must be evaluated individually on its own merit.

For example, consider the following list of claims: The sky is blue, 3 + 3 = 7, water is made of hydrogen and oxygen, Amun-Ra is the supreme ruler of the universe. Just because the sky is blue and water is made of hydrogen and oxygen, that doesn't suddenly make 3 + 3 = 7 true. Likewise, the fact that Amun-Ra isn’t the ruler of the universe doesn’t somehow change the color of the sky. Each statement stands or falls on its own.

In the same way, we can’t put someone on trial for stealing a laptop just because they previously stole a bicycle or set fire to a dustbin. Prior actions may inform suspicion, but they are they are never evidence for a completely separate accusation. Each charge requires its own evidence.

So the answer to "Why wouldn't it be?", would be - "do you have any evidence they are?"

Circumstantial evidence suggests this might be related to the authenticator addition. Perhaps an attempt to acquire access to such information?

I remember something very similar was discussed here like a year ago and I think it was mentioned it was legit but only appears in the US if I remember correctly. Never seen it on my end but I always have ad blocker running

Someone else got the same offer on mobile:

Holy shit, I completely missed that. I can't even... "hey, wanna see me break more games? like & subscribe and join my patreon!"

Alright, I agree that this looks kind of spammy and fishy. It is GOG's love for retro styling gone wrong.

But if you ignore the fight-or-flight impulse for a second and take a closer look, you'll see that the popup just asks you to sign up for their newsletter. Well, it's an SMS newsletter which I haven't encountered before (I prefer email instead), but different countries have different options I guess, same as with payment options.
