If I run a Freenet node, can others access information on my computer?
No. Freenet nodes only serve information that has been deliberately inserted by someone who wanted the information to be shared. Since the code for the project is all open, you can examine it yourself to verify this. Of course, if you or someone else does deliberately insert information that you would rather keep private, you have little recourse. It is likely that the damage caused by leaks of personal information to Freenet will be small in any case. When the source of such information is identifiable, traditional legal remedies can be applied. When the source is anonymous, such information will have no credibility.
