A while ago I remember having a discussion about advertisements done through submissions and having some policy regarding it, and most importantly I remember the infamous dreamcast getting a lot of his Patreon advertisements removed from being cropped

Blitzdrachin has been doing this for quite some time, with the plea to people to subscribe to her Patreon with a disclaimer for people to use the blacklist if they don't like it. Cropped even has its own tag, funnily enough.

Did something change since ? Am I missing something ? I tried to look for any rule changes about advertisements and crops and couldn't find anything. Is there any reason why it's fine for her but not for another person to do it ? I do have the feeling that Dreamcast's ads were by far worse with P logos everywhere, but for obvious reason I can't confirm it anymore, but the question still remains to why it is fine for someone to advertise this way with cropped previews but not someone else
