Disappearing comments..? (Patreon)

Hey everyone, I've been noticing that people's comments have been disappearing. Someone mentioned it once before but I thought it could have been a small glitch or something but now it's becoming more frequent and I don't know why its happening. Is it just my page or is this a common occurrence among other pages too? I discovered that I'm able to delete comments but can other people delete others' comments?? Just to let everyone know I haven't deleted a single comment since this page started, I enjoy reading comments unless I sense it to be spoilery then I stop and save it for another time. Usually the comments are gone before I even get to read them so that kinda sucks. So yeah just wondering!
