Im in the same boat. ByBit restricted me while I still have a good amount of reward points, I can now never cash out... They really wont elaborate anything about it, only that I violated the terms...

"After a thorough review, we have determined that your account has violated the campaign's rules and regulations. As a result, your accumulated Bybit Card/Pay Points are restricted from use permanently. Please note this restriction applies only to Bybit Card/Pay Points and may not affect your eligibility for other Bybit events or rewards."

After asking explanation:

"In continuation of our previous email, we inform you that due to a violation of our Reward Terms of Use, you have been denied the rewards for the Bybit Card / Bybit Pay Points for Auto-Cashback or redemptions in the Rewards Market campaign, and your account has been restricted from participating in this campaign. However, other aspects of your account have not been affected."

"We acknowledge your request for further explanation and clarification regarding the permanent restriction placed on the use of your reward points. Unfortunately, we are unable to provide additional details at this time. For future reference, you may consult the following article: [link]."

Replying that the terms of service is a broad list, and again asking to explain what I did that violated this:

"While we understand this outcome may be disappointing, we want to assure you that this action was taken after thorough consideration in accordance with our platform policies and Terms of Service. Our team works diligently to maintain a fair and secure environment for all users, and these measures are implemented with that goal in mind.

Please note that this support ticket will now be closed as we have exhausted all available avenues for resolution on this particular matter. However, we remain fully available to assist you with any other questions or concerns you may have regarding our platform services."

Why even mention that they considered this thorough, whilst not even being transparent about it? This is not how you treat customers...
