'Privacy Settings' was the first place I went to, and to my knowledge there's no option on there for this.
There's
'Feed posts on your profile Visible to: Users Only' - But as far as I'm aware, that's for viewing my posts directly on my feed? And testing that logged out in a private browser (no cookies/cache/history) - and the posts on the drama feed pages are showing up completely publicly to everyone, not just users. And I don't want them publicly there all the time for other users anyway after the initial posting to the feeds, or going directly to my own feed which is out the way.
'Default tagged posts setting Default: No' - No idea what that even means, but I tested turning it to 'No', and same thing - my posts are showing up completely publicly on the drama feed pages.
'Comment history' and 'Liked content history' - are set for 'Only Me' as well - but they're for those specific sections and are working as selected.
But any drama posts - whether old 'friends feed' posts from before the 2017 update (that should only be visible now to people on the friends list, but was preset by MDL to public), or 'global feed group' posts recently (that technically should only be for people part of the group) - all are showing completely publicly: e.g.
https://kisskh.at/3265-kimi-to-ita-mirai-no-tame-ni/feeds
https://kisskh.at/2461-wakaba-no-koro/feeds
https://kisskh.at/783314-exit-8/feeds
https://kisskh.at/702407-noise/feeds
That's just a small example. And there's no way I can find and give you every single drama comment from the past manually for you to deal with on a case-by-case basis. And how many others will have to go through that as well, and how much time do your staff have to go through all of that when you are busy with many other things?
Please provide an option for us to enable/disable our posts from showing on the drama feeds - like you have the option to do so for comment & like history sections directly on our profiles.
Not all of us want our old comments sitting publicly and to other users all over the MDL website on a permanent basis. We should be able to make a post on the feeds for it to be there for a short time for others to view, and then once buried down the mass of posts, and past the 2 week limit that I noticed on my friends feed - then is just there directly on our own feeds.
