i, and probably many others as well would not like porn to randomly appear on our homepage, this is nothing personal, but forcing porn on people is not right, I understand that many are new to lemmy/kbin so they might not have seen the option to flag posts as NSFW, but please edit this post now that you know and apply it
this is possible, however due to a bug many posts still appear on many clients/instances, even if the community is nsfw, the only way to fix this is to set individual posts as nsfw
