see in my last team death match i went 33 and 8 by camping but i got a care package and i got swarm so i used it and the enemy could not go 5 feet with out dying because of my swarm they spawned in and just died as my video i just posted to this site shows it was bad so i was wondering is it cheating since i have no control where the swarm hit
Spawn trapping/camping isn't against any actual rules, but it is usually frowned upon by a lot of people.
In this case though, it's not even "really" spawn trapping as it's not like your whole team is there waiting for them and killing them. It's just a Scorestreak doing what it's supposed to do, and even then, you only got the Swarm based on total luck, so it's not like you can really be held accountable either.
The swarm technically isn't a tool used to spawn trap people it covers the whole map with a bunch of hunter killer drones. If he was using an A.G.R. and he threw it in the enemys spawn or an escort drone which is personal air support and he camped out in the enemy spawn then that ais a more reasonable example of spawn trapping someone, but whos to say he can't do this. All you are doing in these cases is using strategy to get the most out of your kill streaks. You're not killing them first hand.
using a score streak is using a score streak.
swarm would get the enemy no matter where they spawn lol.
