Mis Information?

I know there is an artical about myths of ACTA but what is fogotten about is once ACTA is in enforment it can be changed and added to without any voting and just gets enforced. Do you really think they aer going to refrain from adding more.

I appologise if I have any bad information and I know there is alot out there but the most important thing is we need to stand up against ACTA as there is alot of truth about what is happening.
