Too many people do that, I'm not one of them.
Yes, I know sometimes you can press skills accidentally, but one skill isn't rushing.
If someone "accidentally" does a combo until someone dies or they shoot with the combo by "accident", that's a rush. If you keep getting "poked" with skills, and you ask them to stop and they don't, that's another form of rushing.
Like Ardon said, do those things to avoid rushers if you're really that scared of being rushed.
