Don't know if I really need it, but to be safe, I log into multiple computers, and I don't want to be banned from logging in on multiple computers. I also share computers with another user.
I am an adult player and have been playing since the end of November of 2006. I logon in spurts. Sometimes I go weeks without logging in, sometimes I login multiple times a day for long or short periods of time and sometimes I login for a short period of time once a week or so.
