Adam Smith's dashboard

When I click on my followers listing on my iPhone there are all these nasty porn people. When I click on them to try and delete them, it says "Server Responded with an Error Not Found". There appear to be several on all nearly every page of everyone I know. I tried logging in on my laptop to delete them that way, but they don't appear when I log in from a computer, just on the iPhone. How can I get rid of them? Really frustrating. Young kids follow me. Not cool for them to be exposed to this.
