Consider this topic:
Among popular links, it lists radikali.ru, which is a photohosting:
In the topic, there are no links at all.
I suppose the links were for the photos to the photo-hosting. However, my Discourse instance is configured to download and store all images locally. So, not sure why that link is in the “top links” list. I do not want it and it makes no sense - is this a bug? If not, how do I remove the link from that list?
