(adsbygoogle = window.adsbygoogle || []).push({}); I've been doing Zombieland and other gamemodes in public match pretty much all day for 2 days in a row and not got a ban, I installed all the DLC and the fixes and I couldn't connect to the BO2 servers about an hour after using it online even though a friend was still on there, so it's not a server issue. the next day I got rid of it and I was back online no problems, so was I genuinely having trouble connecting, or tempa banned? I read that not being able to connect means your ip and account is banned, but not sure if that's true. anyways, is it safe to use DLC installed from pkg's online?

It is safe, but make sure you download the correct fix and pkg files for the DLC.

Yes DLCs are safe to run.
