All I have to say is LOL.
Bungie has finally decided to go out and actually ban some people who have been cheating.....and the forums are salty as fuck right now. WHY WAS I BANNED ERMAGEHRD. Because you are a cheating little piece of shit, thats why.
Destiny does not have dedicated servers. It is all peer to peer. Basically, it has one of the worst overall connections I have seen in any FPS.
There have also been a decent number of cheaters. The most common kind are the lag switchers, but there have been people as well who have DOSed people.
These are fairly uncommon to come across, but I have been noticing quiet a lot of people randomly teleporting around, not taking damage, and shotgunning people in the face.
Bans for cheaters is always a good thing.
