The domains that I have parked at Dan are not resolving within 20 seconds. The problem is solely caused by Dan and is not related to the registrar or ISP. Based on the fact that other people's domains resolve instantly, I believe that Dan is intentionally discriminating against me and possibly others.

 While it is possible that there are others who are experiencing the same issue, I am not sure whether this is a widespread problem. It is evident that users are not being treated equally by Dan. There may be others like me who are affected by this problem. It is necessary to investigate Dan's criteria and determine the cause of the issue.
Even if they are unaware of the problem, they are still responsible for it and must find a solution.

The parked pages have always loaded quickly, but perhaps someone on the forum has experienced a similar issue and found a solution.
Would there be a variation in results if the pages were directed internally towards their marketplace?

Your accusation against the company for discrimination and dishonesty is significant. However, it is essential to provide evidence to support such claims. The responsibility lies with you to substantiate these allegations with more than just your personal beliefs.

Moreover, it is pertinent to question why Dan.com would discriminate against you. What reasoning or motivation do they have? Wouldn't it be easier for them to not have you as a customer than to discriminate? It is vital to consider possible reasons for slow loading times before jumping to conclusions.

For three weeks, Dan.com has suspended my account and not responded to any inquiries. The chat is pointless, and they block it as well. Although they were initially unwilling to answer questions, the situation is even more unclear now.

The office seems strange, but I still liked it. Most of the domain names on their platform have been added many years ago, and I added my last domains in February. In May, my account was still operational, but unfortunately, none of my domains sold. These domains have been listed on SEDO.COM for several years now, and I still use my SEDO account. Occasionally, I receive requests to buy or sell domain names, and most of them are the same as the ones listed on Dan.com, except for a pack of 2s .WS domains that I acquired through auctions.

Dan's intentional throttling of domain resolution times is a clear case of discriminatory behavior. As a domainer, I've seen firsthand the devastating impact this can have on online businesses. It's unacceptable that Dan is prioritizing certain domains over others, and it's time for them to be held accountable.
I demand a thorough investigation into this matter and a solution that ensures all domains are treated equally.
