If I were an artist...

Most artists like to show off their work on the internet where thousands of people could see it and they could change it however they wanted. In my opinion, I do not think that that is a smart decision. The artists can publish it in any way besides putting it on the internet. And after they put it on the internet, they whine about how people are stealing their work and changing it. Just don't do it in the first place. For example, on youtube, there are thousands of people imitating an artist's work. not many artists have a problem with that. So what I'm trying to say is don't publish your work on the internet if you have problems with people commenting and criticizing your work. if you don't have a problem with the rudeness of some people, then by all means, do it. But just keep in mind that not all people are nice and polite.
If you think that you can delete all the nasty, mean comments before anyone can see it, then you're wrong. Someone is BOUND to see it. There's a good chance that you might not be online when someone comments on your work. You can always go to your profile and delete the comments, however, most of the time, you might be too late.
Also, do not post anything on the internet before you're one hundred percent sure. If you post something and after a few weeks, even days, you decide to take it down because you're not so sure, you're too late again. THOUSANDS of people will already have copied and pasted it somewhere you don't know. So don't put anything on the internet before you are sure that it is what you want.
