Why? Read the persons profile. Truth seeker is in the first line of a of his favorite quotes it seems no crime there. 911 means more things in this nation than the WTC. It also means 911 as in the Emergency services call number. Now what does a 911 dispatcher do for a living? A truthseeker perhaps? When we start going on usernames as reasons for being suspect then parnoia rules. If I had that name before the date and it could be taken by some as related to the terrorist acts of 11 Sept. then I might be inclined to use another name as well. But the account is still active just no recent post. Again a common event in a forum this big.
I agree we don't need to check them out if they were just common posters here.
