Alright, now I realise this is hardly crucial to the enjoyment of the site, but it doesn't seem normal, so thought I would mention it. As the title suggests, I have noticed in the past couple of days that a lot - if not all, I haven't thoroughly checked - of the older comments on my images have vanished into thin air. Since there are so many comments from different users gone, I think comment deletion is out of the question (if that is even possible).
Any reason this could be happening?
