How long must I wait for a GM to get back to me about a report?

this doesn't really sound like a drop everything emergency, im sure they will get back to you when they can, until then you will just have sit patiently and perhaps learn to cope.

i swear some of you people act like spamming an emote is causing you actual harm, if youre so high strung over something that minor maybe turn of the internet and go back to single player for a bit.

It's even worse, the only macro and sound effect spam I've seen in Frontlines is from people who actually care about playing the game instead of AFKing, and leading the team by telling them where to go, who to attack, what objectives to pursue. Unless OP has evidence to the contrary, it looks like they got upset that they have to actually play the game instead of mindlessly wandering around and doing nothing for 10 minutes.

I agree, its a classic case of "report them for using the chat box for its intended purpose"
