There's no such thing as "targeting", as long as you don't insult/stay on topic you can't be warned. And tbh, who even have time to target someone.. online.. on a forum...
Yes. Not because I would want to target that person but I think the reporting would happen a lot less. Most people who report I'm sure are afraid of admitting it was them and they cowardly do it anonymously because they feel they have something to gain and/or make a game out of it.
