Bit weird that pinning counts as a reply

Hello,
staff actions such as closing, pinning etc… are counted as replies. I think you can hide it via this CSS. This may be annoying in other UX stuff

.small-action {
  display: none;
}
.small-action.time-gap {
  display: block;
}

Or like I do sometimes, I just delete the action made by staff as this deletes the reply
