If this quote is authentic, her accusations are anything but groundless:

Thanks for writing in. If there is any chance that Rachel will receive spam from a stalker on her project, she should not create one. We simply cannot allow a project to become a forum for rampant spam, as her past project became. If this happens again, we will need to discard the project and permanently suspend Rachel’s account.

If this quote is fiction, then it will be easy for kickstarter to say so.
