No, you cannot get banned on deviantart because of your profile picture.
(a lot of people put inappropriate parts of their body and they do not get banned)
If you do not have permission, or give credit to the origional artist, someone can report you and yes, you may be banned.
No.
this comes with a paid account only
Move the mouse over your icon at your page,then when you see the little pencil thing pop up around the icon you can upload it.
You can't ban them,you have to report them to the help desk,just goggle DeviantART help desk and you should find it,then file a report with details, on whom your reporting to and the staff will decide if they are banned or not.
To use a "plz" account icon, it's just like using a normal deviant icon. For example, if I wanted the icon of the account "horseplz", I would type :iconhorseplz:. Just take the account name, and type :icon_____:. You must use the colons at the start and end, of course.
You can't, YouTube banned them in 2008. If you see someone with an animated icon then that means they had it before 2008 and YouTube allowed them to keep it.
