#1. Don't worry about downvotes. They won't influence your sanity or health. Take it easy. #2. People are jealous and ignorant so, they'll misjudge you often. #3. Maybe the one you tagged was infamous. #4. Don't mention spam (tagging 20-30) names. #5. Check whether he/she is comfortable with it or not. Don't mention strangers. #6. Even if everything is fine, some people are really shallow and would get offended. Happened with me too. Just don't give a shih about it and be happy.
