Well @cessarespinozaa, no problem at all. But I'd appreciate if you can pin-point the exact content which you think violates copyright authorship.

Regarding citations, I'd like to tell you that not all copyleft material insist for a citation or a credit. So not providing a citation to such material is not a copyright violation according to law. It may not comply with your policy but you can not allege that I have violated any copyright and intellectual property laws. Thanks!
