How can I prove my skill in Logicracy in my other writings on the Internet (blogs, my web pages, forum posts, etc)?
Within Logicracy your user name is unique–so no one can impersonate you there (assuming you have obeyed the terms of service and never transferred an account or password). Throughout the Internet, however, there’s nothing stopping someone from taking the username you use in Logicracy and claiming the skill ratings visible in your public profile are theirs. To prove the ‘you’ elsewhere on the Internet is the ‘you’ in Logicracy, you can add a comment to your public profile that specifically refers to your writings elsewhere. For example, you can have a comment in your profile that refers to your blog, your unique username in a forum elsewhere on the Internet, or a specific USENET post. In those other writings, you can include a link to your profile. Note, however, that a user’s published overall skill cannot be reliable because of the possibility that the user purchased the account (which is, by the way, a violation of the terms).
