lets talk about stolen CSS

So as many of you know, people stealing others CSS’ is something that happens quite frequently. What I dont understand is, how is it that hard to just credit them in their bio or blog post- which is why theres this code you can put in your CSS to help a bit (that is if you are letting others use your CSS layouts :)
It may not stop all stealing (obv) but it can help a bit :]

div#footer::after {
content: " CSS theme made by user here on myspace.windows93.net";
color: white;
