I mean fighting in the sense of arguing and posting tons of comments and posts that hijack entire threads and forums. Like for example, a thread might have 90 comments, 40 are russian shills arguing the pro-russian side, 40 are US shills arguing the US side, and then 10 are actual real people. Because the different shill groups try to shut each other down they get caught in arguments with each other, and those arguments end up making up the bulk of some threads. Especially if it's a contentious MSM hot button current issue for both sides, then it goes wild and normal folk can barely get a word in edgewise.
