This should be a safe space.
Emphasis on the "should be".
I will not comment about truthfulness but about consideration. There are people in our small community of BTS sickfics on here have anxiety issues, there are those who fight depression daily and there are traumas that we do not air in public space because it can distress others. I have dealt with these issues myself, and I write and read fanfiction in this community to help myself cope with those issues.
Suddenly reading angry posts about highly sensitive issues is upsetting, and whether or not these events occurred is not as important to me as how it makes others feel. I am not attacking anyone, or singling people out. I only ask that things of this sort are kept private in DMs with friends or that they are kept separate in a different blog for personal things. This is a sickfic community for BTS fans and our posts should reflect that.
I have unfollowed the people responsible for the post, but truly hope that whatever they are dealing with mentally, emotionally, or physically gets better. This public space is not for those subjects. Please let us enjoy our safe space together and remember that others have feelings and that being mindful of what we post helps all of us.
