I’m going to be more specific about flagging:
If you think “something is starting”, please do not post things that are indirect warnings or could potentially provoke the situation.
That includes comments like:
“Wow! Things are heating up.”
“This thread is getting lively.”
“Uh-huh. Here comes trouble.”
“Here we go again.”
Etc.
That also includes NOT posting photos, gifs, memes, etc. that might provoke such as:
The man eating popcorn gif
People pushing each other
An anvil falling on a cartoon character
Etc.
Just simply flag the post, and post any comments about why you are flagging it in the appropriate box.
