why not member does not take newbie report seriosly. Why allow newbie to register. banned all newbie so you big member free, check below and bann all account
Because the reporter doesn't take thread rules seriously. 
Look at this.
No "Newbie" or, "Junior Member" can post an investigation in this thread. They can however post a link (once) to a thread in the reputation section where their investigations can be investigated and analised.
I rarely contribute to this cheater catching party, I think the contributors there are cooperative with the rules. If you have a good relationship with this reporter, tell him about this.
