What is your favourite service for bloggers?
I'm launching a blog where anonymous users will need to make posts. What hosted blog platform allows anonymous users to publish posts with images?
First of all, do you mean anonymous, as in not disclosing their username to readers, or anonymous, as in not giving any details about themselves even to the blog platform? Or some other sort?
The first kind of anonymity is supported by most platforms. The system will know the username and details, but none of the readers will.
The second kind is a really complicated problem, if you stop to think about it. The thing is, everything you do online leaves a trace. Even an anonymous blogging platform will probably record the IP-address and timestamp associated with the post. And even if the blog platform woudn't by itself record any of the activity, traces of the posting activity would remain in the server logs of the platform. Any connection is also routed through multiple points in the internet, which can record the activity. Any of these traces can be used to compromize true anonymity. There are some internet anonymizers that might be used to do this, however, but each poster would then have to route any traffic related to posting through such a service.
