Is bug abuse a reportable thing?

I've been playing against so many bugged sivirs and they all think that bug abuse isn't reportable. Do they actually get banned for bug abuse if I report them for cheating?

We're testing a new feature that gives the option to view discussion comments in chronological order. Some testers have pointed out situations in which they feel a linear view could be helpful, so we'd like see how you guys make use of it.
