Proton VPN was caught running price sensitivity tests on its own users and then provided a cheap and inaccurate excuse when asked about it. Users on Proton's subreddit (which has since been deleted by the moderators) noticed that they were quoted different prices for the same VPN Plus plan in the same country at the same time. Refreshing the page showed a price of $2.77 per month with 72% off, while opening a new incognito window showed a price of $3.23 per month with 68% off, despite nothing about the visitor having changed. I have conducted the test myself and can confirm this (and you can too, while it is still active). Proton's General Manager responded by saying that there was no adaptive pricing and that a recent sale simply hadn't "universally refreshed".

Windscribe then pulled the actual page source. Each visitor was assigned to a variant and the test was labelled in plain text inside an HTML meta tag. One session returned content "A" and the other returned content "B", with each pointing to a separate pricing URL. One of these was explicitly flagged as "test-300726-b". A screen recording showed the price changing in real time in clean incognito sessions. Expired sales don't do that. Neither do cached pages.

It is good to be precise about the terminology, because Proton was too. Adaptive pricing uses personal data to set a price tailored to an individual. Price sensitivity testing involves quoting different people different prices for the same product in order to establish the point at which sales begin to drop off. The GM denied the latter. Nobody had accused Proton of doing this.

Most major companies run A/B price tests, so it's a completely ordinary practice. However, Proton's entire business is built on trust, transparency and privacy, not just as a feature but as a promise. If you refer to your own labelled test code as a "glitch", it suggests that you are not transparent. For a brand built on trust and transparency, it is the most difficult thing to apologise for.

I know that Kerui Peptide Hong Kong Co., Ltd. (KR) is a well-known supplier, but I always place a small test order before making a larger purchase.

On 10 July, I placed an order with them for KPV. My bank confirmed that the payment had successfully reached the recipient’s account.

After three weeks with no update, I contacted Wangli to ask what was happening with my order. She apologized and said that their broker had failed to inform them about my payment.

She then told me that they did not have KPV in stock and offered me a $50 credit if I placed a larger order with them. I declined and asked for a refund instead. She confirmed that the refund would be processed.

To this day, I have not received a single cent.

I also raised the issue in their official Telegram channel, where she acknowledged the situation publicly. She also admitted it in our private conversation, but later blocked me on WhatsApp.

The contact details were verified and obtained from their official website. I have the full conversation, payment confirmation, and screenshots. For now, I am attaching only a few of them.

I am posting this as a warning to others. If a company is willing to treat a customer this way over a $104 test order, I would strongly advise caution before doing any larger business with them.

Yesterday I spent half a day fighting with the Linux distribution and the Proton VPN client. The experience was extremely frustrating and the amount of errors, freezes, and unexpected behavior was unacceptable for a paid VPN service.

You can see the attached screenshots showing some of the issues I encountered:

• unexpected errors when trying to enable security features,
• the application becoming unresponsive,
• problems with server availability despite having an Unlimited subscription.

For a company that heavily promotes privacy and security, the overall experience feels contradictory. Having a polished Windows application is not enough, especially when many privacy-conscious users are moving away from platforms where data collection and telemetry are major concerns. A VPN application on Windows cannot be the only focus while Linux users are left struggling with instability and broken functionality.

This was another attempt to use Proton VPN, and unfortunately it failed again. Even basic Linux package distribution caused problems, including difficulties obtaining packages from GitHub releases.

Linux users are often the people who care most about control, transparency, and reliability. Spending hours troubleshooting a VPN client that should simply work is not acceptable.

Proton has been promoting its new Linux GUI release as a major improvement, but after actually using it, the experience was extremely disappointing. In its current state, I would not consider this software ready for a public release. For Linux users who expect stability, transparency, and quality, releasing such a client feels like a disregard for the community.

After this experience, I have cancelled my subscription. A paid privacy service should not require users to spend hours troubleshooting basic functionality.

When I buy from a trusted supplier, there is a much smaller volume in the vial. Same composition, same amount. But from the gray supplier, there is much more. Why is there such a difference in 🔊?

Hi I just bought windscribe account. Paid with btc, no email added. You set up itself later if you like. I already have necessary vpns and found windscribe useless to me.

Deal 20€. Payment first. Than credentials. BTC or instant sepa if you like, revolut.
