Too much information?

Sure they can. Take for example somebody says that he falsely claimed to be a US citizen. In the course of an investigation, if CIS learns that the person posts here, they could of course subpoena Mr. Khanna to provide login details, etc. for that person. Has happened, although I don't know about it in an immigration context. For example, the RIAA subpoena'd Verizon to hand over connection logs from their DSL business so that the RIAA could find out who was illegally sharing music files.
Bottom line: don't think that you are anonymous on the Net.
Even the so-called anonymous remailers are not necessarily really anonymous. I remember the servers of a remailer in Norway being seized by police.

In the case of illegal sharing of music, it's a different thing because that is a big money problem which caused a major effort and fight from the record companies to bring about those subpoenas. I don't think that any US attorney in his right mind will support some xenophobe anti-freedom USCIS agent who might think that Jose Immigrant is maybe member AlphaRomeo on immigrationportal.com and spend countless amount of hours researching and preparing a case, to prove probable cause to a Judge to supeana the IP address and use some question posted by this member which can easily be challenged in court.

People here are talking about their personal situations with enough detail that it wouldn't be too hard for someone in the USCIS to out whose case it is. Think about it: people have shared the DO, the dates of interviews, and other very specific circumstances about their case. With that alone, they can quickly narrow it down to a specific case and wouldn't need login records from this site to identify who's posting the information. Then the poster has just given them an open book to start digging into...

Who can narrow the matching information down? There are thousands and thousands of files. Just the FBI by itself has a backlog of 2.5 Million name checks pending. There are Millions of Immigrants' files pending with USCIS and each agent has hundreds and hundreds of files on their hand. Files that keep moving on a monthly basis from agent to another. Yeah, your fantasy would've been believable if each officer had one case with a lot of time on their hand, but that's not true. I am happy that your case was very easy and you got your paperwork in a timely manner. But remember character is ONLY built during a crisis. Now, you are welcome to come and help others who are in need and dire situations, otherwise, please accept my plea to end scaring those who are already scared by a tyrant immigration service.
