For personality rights, we could use like a little head-shoulders icon similar to http://fontawesome.io/icon/user/ ?
For swastikas and hammer and sickles I'm not sure because using the File:Under_section_sign,_swastika.svg wouldn't work very well in one color, but using the illegal symbol itself wouldn't be appropriate.
A generic symbol could be the universal warning triangle sign e.g. http://fontawesome.io/icon/exclamation-triangle/
Here are some preliminary nazi and communist restriction icons. I tried using the Under_section_sign,_*.svg files from Commons for nazi and communist symbol icons, but they didn't work out very well, so I tried using exclamation points instead.
