The day after entering the details of a new credit card on GOG, my bank locked the account due to a suspicious purchase ([url moderated]) originating in Cyprus, where I understand GOG process their card payments. This seems like a very suspicious coincidence and I will no longer trust GOG with my card details.

I recommend using the safer payment options if you're concerned by this.

Reason #44 why a lot of banks automatically freeze your account when trying to purchase from GOG.
These things add up, and more responsible banking institutions don't want the headache.

Use paypal or the equivalent.

I wonder how many of your 68 games were bought, and how many were actually acumulated for free in the 4 years this 0 rep/posts account has existed. But sure, after 4 years you have decided to no longer trust GOG.

Just to make it clear, personally, I suspect this to be a troll post/account.

Troll or not, this hardly proves anything. I bet majority of GOG clients never posted here once and over 60 games in 4 years is not really small number (but that sign of times I guess, nowadays if you don't have 1000 games you're automatically suspicious as troll or alt account :P).

This seems to be some strange advertisement for that shady site, or maybe the OP used their card on that site. As far as I remember, GOG moved all their business from Cyprus to Poland a few years ago.

Yes - there was a big thing about it at the time it happened. GoG is as secure as any other online store that you might use - I've used them for about 13 years and never had an issue with my card in that time. You're more likely to have your card scraped in a bar or a filling station than on GoG.

At least OP was using a credit card and has the benefit of all the anti-fraud features of those cards.

All my purchases via gog using my CC have shown up as GOG.com, no mention of this other site.

OP are you sure you didnt sign up this other site at the same time? I checked it and they mention a 3 usd "trial"
or perhaps you are the victim of a scam, as when I googled the site you mentioned it gets mentioned on spanish article about the "brushing" scam that hit a couple of years ago.

Are you sure you didn't you know, use a third party key reseller, but don't want to be called out for it?

Or that you're a spammer subtly advertising for it?

Actually it's more than that. First the outrage of the post, then the fact that he took the time hide his profile. Finally he never posts for 4 years, presumably happily buying and trusting GOG. Then all of a sudden he changes his card and his bank blocks his account due to suspicious activity. So he is done trusting GOG... come on!
And finally he never posts but all of a sudden he makes this thread...

Click bait, outrage troll is obvious... again, in my opinion.

A few years ago, when I switched to a new credit card, this happened to me, once. Because the new card had no history of overseas purchases yet, when I bought three GOG games in the same day, it tripped a "red flag" filter. I discovered it when I was unable to buy booze at my local liquor store, which had me feeling a bit cranky.

Fortunately, I've used the same bank for over a decade, and it took a teller all of about ten minutes to resolve the situation completely with their credit division. The issue had nothing to do with GOG, just my bank being a bit over-zealous with their anti-fraud protection. On the whole, I'm ok with that.

There are things about GOG that annoy me to no end, but almost 700 games in, and they have never bobbled a payment, never failed to promptly refund me for returned games. Wish I could say the same about my internet, tv, phone, or Amazon!

Whenever unusual activity occurs on a credit card bank security departments act with caution, this is normal. GOG's payment processor is in Cyprus, and unrelated to that there is a lot of fraudulent activity made by others in the world that pass through Cyprus also, and banks know this so when they see a new payment going through Cyprus for the first time they may err on the side of caution and disallow the transaction until the owner of the account confirms that it is a legitimate transaction being made and not fraud or card theft.

You need to communicate with your bank that the transactions to GOG are legitimate and not fraudulent, and they will put this on record and allow payments to GOG in the future without triggering security alerts over the transaction.

This isn't unique to Cyprus, but this can happen whenever any bank detects a transaction that is statistically unusual for the card holder to make compared to past habits, or if any other statistically relevant risk factors exist where they are unable to determine the legitimacy of the transaction on their own. They are likely to err on the side of caution until the card holder informs them that they did in fact make the transaction and it is legitimate.

There is nothing unsafe about GOG processing payments in Cyprus.

ponczo_ removed the site name from the first post. Now people seem to think this thread is about a card being locked due to a transaction from a foreign country. OP actually mentioned a different site name appearing on the transaction. I see no legitimate reason for that to happen, and the site in question shows up in articles about fraud, as mentioned above.

On a related note, I don't think payment processing happens in Cyprus anymore. This post from 2014 mentions Cyprus in the Terms of Use, but there's no mention of it now.

Anyway, I don't know what happened here. In 2½ years I haven't encountered anything like this, and only GOG.com PL showed up on the transaction details.
