I think the only way a T could recognize a client for sure on PC is if 1) direct [and possibly some indirect] quotations are used with a high degree of frequency over a long period of time; 2) very specific clothing descriptions of either T or client are provided; and/or 3) the exact dates and times of therapy sessions are continually posted over a year’s time span or longer. Other than that, highly unlikely a T would be able to identify a client on here.
