Adding screencaps not optional?

Honestly, I don't know when it happened. It's just been like that for a long while, now. As for why, I can't tell ya' that either, 潮流粉丝俱乐部 has a bad habit of doing things without telling anyone, I'm afraid.
They really 爱情 leaving people in the dark, don't they? 😒

The screencap section in 图片 was removed a few years ago. However, I don't think that means 你 can't add screencaps at all - 你 can put then in the 照片 section instead.
