It doesn't. Those are two unrelated statements that were read as one.
Sentence 1: references an exploit that was fixed, in order to prevent its usage again. The exploit cannot be 'accidentally' used in any way whatsoever. One must first know about the exploit, want to use it, and be able to use it, before using it. There were folks using an exploit to enhance their abilities. Turbine knows who uses it, and has issued permanent bans to a number of accounts. They will likely ban more accounts.
Sentence 2: refers to gating use of rep items behind newly set levels, in order to restrict/discourage TP farming and creation of disposable characters created for the purpose of acquiring masses of TP.
The previous posts on these subjects should have made this clear.
I hope this helps.
