Whooter. Information revealed by patients at aarc is supposedly protected by patient confidentiality (in the states, a program violating this would be subject to serious penalties). While any information available to admins, such as Ip addresses here, is also confidential, that does not prevent anybody, including admins, from using other, non-confidential or publicly available information to guess at your identity, or even attempt to out you.
In this case, it is clear that there are people using AARC insider (privileged) information to threaten, intimidate, and out people. Big difference. No privileged/confidential information was ever used to guess at your identity (it was actually your own words... who you claimed to be).
