online shooters community

2 questions

1-is black ops 1 still have an active online community and if so is it just all hackers?

2-what other shooters besides cod,battlefield,halo have a good amount of people online playing?

I haven't try coop on Sunset Overdrive, but I would believe that community is running good.

Titanfall.

PVZ Garden Warfare was pretty active when I stopped playing it 2 or 3 months ago.
