Some of it is bot activity. I mean anybody who actually does name their char something jibberish is asking to be called out as a bot even if they aren't. Some of it is definately network latency and packet loss due to the DDoS attack currently going on with a few various ISP nodes. Rubberbanding by itself is almost always lag, not necessarily on your or on SE's side but with some of the ISP's in between. 1 person rubberbanding usually means that person is lagging. 8 would usually indicate you. Not necessarily do to things on your side, but mainly lately due to nodes in your network path being flooded.
