When I get a ping and can't even read the message, and just have to guess what's going on because the chat is getting flooded with one command? Yes, it becomes a bit of a problem.

So what the heck even was that?

No you didn't.

I got an @ everyone ping. I clicked on it and couldn't actually read it because I wasn't allowed to see message history. I had to guess what was going on.

I still can't see it. So no; nothing was explained.

Maybe a little less condescending?

So what happens when the people who were offline for the last few minutes show up? They won't be able to see the message history, so they won't know what's going on.

Why do you ping everyone TWICE when you upload?

Yes, but why though.
