We're aware of an issue with ads on the site getting duplicated to annoying locations and are still triaging the cause. This is probably an issue caused by Google, because we haven't changed the Guild-side advertisement code.
If necessary, install an adblocker until this issue is resolved.
To add on this as I'm talking to Legend about it: It is both an issue on mobile and desktop. If you're on desktop, uBlock Origin will remove all the ads for you. On mobile, I'm currently at a loss. I use Opera GX for my phone browser, and the ads get through their built-in ad block feature.
