Let me rephrase your question a bit to clarify this for you.
"Someone broke the rules, so I broke them as well - right back at him, am I going to get in trouble?".

Someone else breaking our TOS doesn't give license to do so yourself. I know interactions like this can be frustrating, but /ignore is far better than a retort.
