Curse has implemented a system for requesting consent for marketing and tracking, this system uses the URL you're seeing in your console to provide information on the different purposes of tracking, and get a list of the various third party services. This is completely safe, not something to worry about
If you're using privacy and ad blocking plugins you may not have seen the prompt to consent to tracking, try visiting the forum in incognito mode to see it, it's the big purple banner at the bottom of the page. If you click "Learn More" below the "Got It, Thanks!" button you can then choose from various options, and next to earn option click "Learn More" to see the per-third party break down which is sourced from the URL you've seen.
