The new terms of service announced recently include an arbitration clause. The new terms specify that one can opt out of arbitration by sending a letter including their name and their mailing address to Stack Overflow.
So far users have been able to use the site equally whether they wish to use their real name (as I do) or remain completely anonymous. I find this a cornerstone of an online community like this. But now this has changed: It appears that an anonymous user has to disclose personal information to opt out of arbitration and gain better legal protection should anything go awry.
How can a user opt out and still remain anonymous? Is it possible at all? And if there is a way, how do you identify the user?
I wanted to ask about this specific situation separately, as it is not covered by the other question about opting out.
